The Protein Question

I am always (read: ALWAYS) getting asked about protein as a vegan, and that became a question posed with even greater intensity and looks of alarm when I transitioned to a 100% raw-vegan diet. Despite decades of available information (think Frances Moore Lappe and John Robbins) and an ever-increasing exposure to a variety of cuisines, there still seems to be some sort of block on the protein "issue". Recently I ran across this thread on a favorite raw forum I hit up for recipes (when I have the time!), containing an excellent -- clear and concise -- summary by contributor 'Evigail' on just how our bodies utilize amino acids (the building blocks of proteins) from the food we ingest and how a plant-based diet can meet our needs. So I'm posting it -- in part to share useful information, but selfishly to have a post to direct the questioners to when I don't feel like having to explain myself over and over and over and over again...
