There are no "protein rich vegetables." The most you'll get per serving of a given vegetable is 3 grams. However, they do make Vegetable Protein Powders. I bought some
Pea Protein by Now Foods. It tastes disgusting on its own, but if you add some stuff to it like natural cocoa powder, almond milk, and cinnamon it makes it drinkable some what.
Has anyone seen
Fat, Sick and Nearly Dead?
