A typical 1 patty serving of veggie burger contains 15.7 grams of protein (15.7 g per 100 g), which makes it a very good source of protein. That covers roughly 31% of the 50 g reference Daily Value, so it can anchor a high-protein meal for the day.
Protein accounts for roughly 35% of the calories in veggie burger, making it very 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, veggie burger ranks 7th by protein per serving, and 231st out of all 796 foods on the site. Set against natto, another soy food entry in the database, a serving carries about 1.4 g less protein (natto has 17.1 g per 1/2 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 100 g. Because pieces vary, the per-100 g figure is the one to use when comparing this against a food measured a different way.
