Here's how I manage to "get the bulk of my protein": I don't. Screw protein :) All of your protein needs are met without even thinking about it becaaaauuuuuusee...PROTEIN IS EVERYONE. So other than that, all fruits contain all essential and conditional amino acids. It's all the protein--and more--thank you'll ever need...WITHOUT putting your body in an overly-acidic state.
Chew on dat :D
