Find out which burgers packs the biggest protein punch.
Ready-made veggie burgers offer a great way to keep your saturated fat intake in check and add protein to meatless diets. Even though soy-based burgers and black bean burgers are naturally cholesterol-free and have similar calorie and fiber profiles, soy provides a bit more protein, which is welcome in vegetarian diets. Soy burgers also contain twice the amount of calcium and iron―nearly 10 percent and 22 percent of the recommended intake, respectively. However, they also contain more fat. Try either or both of these meatless burgers, and choose the one that you like best.
