Preheat oven to 400 degrees.
Combine all ingredients in a large mixing bowl. Use your hands to thoroughly mix the ingredients until the mixture is uniform.
Spray a cookie sheet with cooking spray and form 1 and half inch meatballs (roughly half dollar sized). Place the meatballs on the baking sheet.
Cook the meatballs for approximately 25-30 minutes. To determine whether they are done, I usually cut one meatball open (from the center of the pan) to make sure that it is no longer pink in the middle.
Allow the meatballs to cool to room temperature (approximately 1 hour). Put the meatballs into quart sized resealable freezer bags. Be sure you remove as much air as possible from the bag. Label the bag with the contents and date. Place in the freezer until ready to use.
To thaw, simply remove the desired number of frozen meatballs from the bag and microwave until hot (usually 2+ minutes - just check to see when they feel heated throughout).
