Depending on how much of a vegan you are you can use all kinds of foods for protein........eggs, PB (natty), beans, Gimme Lean (meatless sausage), meatless burgers & crumbles, TVP (it's like ground beef).
You can also add flavorless protein powders to foods like pancakes, etc.
I had to go back to eating meat cuz I couldn't get enough protein myself...
