Tofu, beans (they'll start seeming more delicious the more you eat them), dairy, eggs, nuts, lentils, tvp. Most grains have some proteins in them, but usually need to be paired with something else to make a complete protein. Quinoa is an exception.
I've been making a killer veggie burger lately. Freeze, then thaw some tofu. (This is a little quicker if you slice the tofu into thinner pieces.) After it's thawed, you can squeeze the excess water out of the tofu. Crumble or grate it into a bowl. Add some breadcrumbs, an egg, some soy sauce, minced garlic, minced onion, and some flat leaf parsley, and seasonings as you please (salt, pepper, parmesan cheese, chili flakes, etc) Form into patties or meatballs or meatloaf. Delicious! You'd almost think it was bad for you!
