A typical 1 large egg serving of cheese omelet contains 8 grams of protein (13.4 g per 100 g), which makes it a good source of protein. That covers roughly 16% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Protein accounts for roughly 31% of the calories in cheese omelet, making it moderately protein-dense. The rest comes from fat and carbohydrate, so it adds a solid amount of protein while still carrying real energy - useful when you are eating to a calorie target rather than under one.
Among the 20 eggs in the database, cheese omelet ranks 7th by protein per serving, and 351st out of all 796 foods on the site. Set against egg salad, another egg entry in the database, a serving carries about 0.4 g more protein (egg salad has 7.6 g per 1 large egg).
It is a complete protein - it supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own. The serving above is counted by piece at 60 g. Because pieces vary, the per-100 g figure is the one to use when comparing this against a food measured a different way.
