A typical 1 patty serving of meatless sausage contains 7.7 grams of protein (20.3 g per 100 g), which makes it a good source of protein. That covers roughly 15% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Protein accounts for roughly 32% of the calories in meatless sausage, 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 31 soy foods in the database, meatless sausage ranks 18th by protein per serving, and 361st out of all 796 foods on the site. Set against unsweetened soy milk, another soy food entry in the database, a serving carries about 0.8 g more protein (unsweetened soy milk has 6.9 g per 1 cup).
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 38 g. Because pieces vary, the per-100 g figure is the one to use when comparing this against a food measured a different way.
