Preheat the oven to 350 F if baking instead of frying.
Drain and rinse the beans very well.
Combine everything in a food processor until evenly blended - stop while it still has some texture but no large pieces remain.
Roll into balls (small meatballs cook much more evenly).
Either pan fry in a little oil, or place on a parchment-lined baking tray and cook on the center rack for 10 minutes, then turn each ball and bake an additional 10 minutes or until desired texture is reached.
