This is a very difficult topic and is too broad for me to explain in full. Any information I were to give would be specifically suited to the San Diego plant life. I recommend professional/volunteer wild edibles classes.

Also with animals, I know how to catch and cook the wild life around San Diego but that's about all. And besides, we both know that I don't want to write out directions and you don't want to read them. I again suggest a qualified class.
