As you may or may not know there is a local Food Not Bombs chapter in Phoenix. I recently began re-attending and they are in desperate need of volunteers to cook/prep/serve/clean. There is no set amount if time you must come. Typically they begin cooking/prepping food at someones house around 11am Sundays and cook till 230pm. Then they transport the dishes to the park next to the large Phoenix library and serve. Anyone can come eat, and anyone can come prep. If you have the time or know someone who can help please feel free to come down.
