Vega (free of soy and whey, etc)., hemp portien, pea protein, brown rice protein, beans, lentils, NUts and SEEDS, and all vegetables have some protein in it. For example, if you look at artichokes and okra, the proetin to carb ratio is pretty ideal.
Robert gets pretty big and he has no problem getting enough protein. Here is one of my favourite pics of him. Maybe he can chime in on this thread as well. We have a few bodybuilding big guys here, so you can get big and bodybuild on a vegan diet. Will Peavy has a good before and after pic somewhere here too, and is thinking about getting into competitive bodybuilding. Anyway, here is that pic I promised of Rob.
