Place all ingredients in a medium bowl, and mix with hands until everything is incorporated. (Do not overwork, or meatballs will be tough).
Form into golfball sized meatballs (will make about 22-24), and place in a single layer in a pan. (Parchment paper makes for easier cleanup).
Bake at 350° for 20 minutes.
Use immediately by heating in sauce, or freeze until needed.
