lentils!!!!! mmmm

you can cook these up to be spicy too..adding cumin, chili, etc and using in chili or stew or w/ brown rice.
Quinoa ( a grain) is an absolute supa-food! its got all the aminos and protein that you need, its totally complete. you can eat it sweet and warm like oatmeal, or savory, to replace rice in any dish (pilaf is my fave.... so i make it orzo pasta and quinoa w/ veggies and balsamic/oil/seasonings) they also have quinoa pasta.
Seitan has alot of protein and is delicious and easy.
tofu can be seasoned/ marinated any old way, and added to sandwiches, stirfrys, salads. one of my faves is to simply saute up the tofu in a pan, then add taco seasoning, then add to a tortilla w/ refried beans, and other toppings.
hummus is made w/ beans, so lots o' protein. i love black bean hummus!
you can also toast chickpeas and season to put on top of salads as well.
edamame...eat plain, salted..or put in salad, soups, etc.
