A calorie is a unit of energy that is present in food, which provides the body with energy and fuel to function. The number of calories in an egg white, tomato, and cheese sandwich depends on the ingredients and their quantities. For example, an open-faced egg and tomato sandwich contains approximately 285 calories, while a Woolworths tomato and cheese sandwich on white bread contains 217 calories. The addition of egg whites will increase the protein content and, thus, the overall calorie count.

What You'll Learn

Calories: 285 in an open-faced egg and tomato sandwich
An open-faced egg and tomato sandwich is a tasty and relatively nutritious option for a meal. This sandwich has 285 calories per serving and offers a good balance of macronutrients, with 21% carbs, 56% fat, and 23% protein.
To make this sandwich, you'll need an English muffin, an egg, some tomato, and cheese. Start by toasting the English muffin and topping each half with tomato slices. In a separate skillet, heat some oil over medium-low heat and gently cook the eggs until the whites are almost set, which should take about 1 to 2 minutes. Place a slice of cheese on top of each egg, and cover the skillet for a minute to melt the cheese.
The calories in this sandwich come primarily from the egg, cheese, and English muffin. A large hard-boiled egg contributes about 78 calories, while a slice of whole wheat toast adds 70 calories. The tomatoes themselves are relatively low in calories, with a large, raw, red, ripe tomato contributing about 38 calories.
Compared to a traditional egg and tomato sandwich, the open-faced version may offer a slightly different nutritional profile. For example, a pre-packaged egg and tomato sandwich from Waitrose contains 359 calories, with a macronutrient breakdown of 34% carbs, 46% fat, and 20% protein. This variation in calorie count and macronutrient distribution may be due to differences in ingredients and portion sizes.
It's worth noting that adding cheese to your sandwich, as suggested in the recipe, will increase the calorie count. For example, 10 grams of Gouda cheese add about 36 calories. If you're watching your calorie intake, you might want to consider the type and amount of cheese you use, or opt for a different sandwich variation altogether.

Macronutrients: 21% carbs, 56% fat, 23% protein
An egg white, tomato, and cheese sandwich is a nutritious option, offering a good balance of macronutrients. While the exact calorie count and macronutrient composition can vary depending on the specific ingredients and serving size, I will focus on the macronutrient profile you provided: 21% carbs, 56% fat, and 23% protein.
Carbohydrates, or carbs, are a vital source of energy for the body. In a sandwich, the primary source of carbs comes from the bread. Whole wheat bread, for instance, contributes about 70 calories per slice, offering complex carbohydrates that provide sustained energy and essential nutrients like fibre.
Fats, the most energy-dense macronutrient, play a crucial role in satiety and the absorption of certain vitamins. In this sandwich, fat sources likely include cheese, oil used for cooking, and the natural fats found in egg yolks. For example, 10 grams of Gouda cheese contribute about 36 calories.
Protein is essential for various bodily functions, including muscle repair and growth. Egg whites are a rich source of protein, offering about 78 calories per large egg. Additionally, cheese also contributes to the protein content of the sandwich.
The percentages provided indicate that this particular sandwich leans more towards being a source of fats and proteins, rather than carbohydrates. This could be beneficial for individuals following a lower-carb or ketogenic diet, or those focused on increasing their fat and protein intake.
It is worth noting that the cooking method can also impact the macronutrient profile. For instance, frying an egg in oil will add more fat calories than using a non-stick skillet, altering the overall fat percentage. Similarly, the type of cheese and bread chosen will affect the final macronutrient breakdown.

Daily value: Good source of protein, calcium, and vitamin A
An egg white, tomato, and cheese sandwich is a good source of protein, calcium, and vitamin A.
Egg whites are a great source of protein, which is essential for muscle growth and repair. They are also low in calories and cholesterol, making them a popular choice for people on a weight-loss journey. In addition to egg whites, cheese is also a good source of protein.
Cheese is also a source of calcium, which is important for bone health. Other sources of calcium include milk, yoghurt, and starchy foods.
Vitamin A is found in many animal-sourced foods, including cheese, and is essential for maintaining vision, growth, immune function, and reproductive health. It is also found in vegetables such as spinach and carrots, as well as fruits like apricots and mangoes.
This sandwich can be a nutritious and filling meal, providing a good balance of protein, calcium, and vitamin A, while still being low in calories. It is a versatile option, and you can add extra vegetables and healthy fats like avocado to make it even more nutritious.

Variations: Calories vary depending on bread and cheese type
The calories in an egg white, tomato, and cheese sandwich can vary depending on the type of bread and cheese used. For example, an open-faced egg and tomato sandwich on an English muffin with cheese has around 285 calories. The calorie count for a similar sandwich on whole wheat toast is lower, at around 178 calories.
The type of cheese also makes a difference. For instance, a sandwich with gouda cheese will be around 36 calories from the cheese alone. A sandwich with cheddar cheese will likely have a higher calorie count, as cheddar tends to be more calorific than gouda.
The bread type can also affect the overall calorie count. A sandwich on white bread will have a different calorie content than one on whole wheat or rye bread. White bread typically has more calories than whole wheat or rye options. For example, a Woolworths tomato and cheese sandwich on white bread contains 217 calories.
Using an English muffin instead of sliced bread will also change the calorie count. Muffins tend to be denser and have more calories per gram than sliced bread. So, a sandwich on an English muffin may have a slightly higher calorie count than one on sliced bread, even if the weight of the bread is the same.
In addition to the type of bread and cheese, the amount of each ingredient used will also affect the overall calorie count. A larger sandwich with more eggs, tomatoes, and cheese will have more calories than a smaller sandwich with fewer ingredients.
Finally, the way the sandwich is prepared can also make a difference. A fried egg and tomato sandwich will have more calories than one made with hard-boiled eggs, as the fried sandwich will include additional calories from the cooking oil or butter. Similarly, toasting the bread may add a small number of calories, as the toasting process adds a small amount of oil to the bread.

Comparisons: A Waitrose egg and tomato sandwich has 359 calories
A pre-made egg and tomato sandwich from Waitrose contains 359 calories. This is higher than the 285 calories in an open-faced egg and tomato sandwich. The higher calorie count is likely due to the use of two slices of bread instead of one.
Comparatively, a Woolworths tomato and cheese sandwich on white bread contains 217 calories, which is significantly fewer than the Waitrose option. However, this sandwich does not include egg. If you were to add an egg to this sandwich, you could expect the calorie count to increase. A large hard-boiled egg, for example, adds about 78 calories.
The Waitrose egg and tomato sandwich derives 46% of its calories from fat, 34% from carbohydrates, and 20% from protein. This is a fairly balanced macronutrient breakdown, though it is relatively high in fat. For those watching their fat intake, an egg white and vegetable sandwich on whole wheat bread is a lower-calorie and lower-fat option.
The open-faced egg and tomato sandwich mentioned earlier contains 56% of its calories from fat, 21% from carbohydrates, and 23% from protein. This option, which likely uses only one slice of bread, provides a higher proportion of calories from fat and protein, making it a good choice for those seeking a more filling, higher-fat meal.
It is worth noting that the number of calories in an egg white, tomato, and cheese sandwich will depend on the specific ingredients and quantities used. The type of bread, amount of cheese, and additional toppings or spreads will all impact the overall calorie count.
