How many calories are in an omelette sandwich?

The number of calories in an omelette sandwich can vary depending on the ingredients used and the portion size. A basic omelette sandwich made with two eggs, one slice of cheese, and two slices of bread may contain around 300-350 calories. Adding additional fillings such as vegetables, meat, or sauce will increase the calorie content. For example, adding bacon, sausage, or avocado can add around 50-100 calories per serving. Using whole-wheat bread instead of white bread will also increase the fiber content and add a few extra calories. To keep the calorie content of an omelette sandwich lower, use low-fat cheese, lean protein sources, and whole-grain bread. You can also omit the bread and serve the omelette on its own or with a side salad.
