A boiled egg with toast is a breakfast staple that can be quite nutritious. Eggs are low in calories and high in protein -- a nutrient that will keep you feeling full and satisfied until lunch. If you leave off the butter, whole-grain toast is low-fat and high in fiber, which is good for bowel health. If you have high cholesterol, stick with the boiled egg white and skip the yolk.
One large boiled egg -- roughly 50 grams -- has 78 calories. If you chop up several boiled eggs and measure out half a cup, you'd be eating roughly 100 calories, according to the U.S. Department of Agriculture's National Nutrient Database.
Sizing Up Your Toast
The calorie count for toast depends on the size of the slice and the type of bread. A regular slice of multigrain toast will have about 69 calories, while a large slice may have up to a 109 calories. A breakfast favorite, raisin bread averages 86 calories in a large slice. Plain white bread will be around 80 calories per large slice but isn't particularly nutritious.
Most people enjoy toast smeared with butter or margarine, but both would increase your calorie count. Half a tablespoon of either has around 50 calories. A better option is sugar-free fruit preserves.
