beans are a great source of protein!

Yes. Your protein requirements depend on your height, weight and level of activity. Since you aren't eating animals (YAY) you need more egg WHITES if that's your main source of protein. Nuts, seeds, beans, tofu and other dairy items are also good protein foods. If you have a small appetite (like me), then it gets more complicated because you need calories too...talk to a nutritionist if you can.

Protein intake in vegetarian and vegan diets is only slightly lower than in meat diets and can meet daily requirements for any person, including athletes and bodybuilders.[47] Studies by Harvard University as well as other studies conducted in the United States, Great Britain, Canada, Australia, New Zealand and various European countries, have confirmed that vegetarian diets provide more than sufficient protein intake as long as a variety of plant sources are available and consumed.[48] Proteins are composed of amino acids, and a common concern with protein acquired from vegetable sources is an adequate intake of the "essential amino acids", which cannot be synthesized by the human body. While dairy and egg products provide complete sources for lacto-ovo vegetarians, the only vegetable sources with significant amounts of all eight types of essential amino acids are lupin, soy, hempseed, chia seed, amaranth, buckwheat and quinoa. It is not necessary, however, to obtain protein from these sources — the essential amino acids can also be obtained by eating a variety of complementary plant sources that, in combination, provide all eight essential amino acids (eg. brown rice and beans, or hummus and whole wheat pita, though protein combining in the same meal is not necessary). A varied intake of such sources can be adequate
