Preheat your oven to 350 degrees and line a baking sheet with aluminum foil and coat with cooking spray. Set aside.
In a large bowl combine all of the ingredients and mix well using clean hands or a wooden spoon. Use a melon baller or tablespoon to scoop out equal amounts of the turkey mixture. Shape into golf ball size meatballs and place on the baking sheet. (It is okay if the meatballs touch. They will shrink in the oven.)
Bake for 15-20 minutes or until the meatballs have reached 170 degrees. Place the meatballs on a clean baking sheet to cool. Once cool, place the tray in the freezer just until meatballs are frozen (about 2 hours) then divide into freezer bags to store.
To reheat: thaw meatballs completely and reheat in a warm oven, microwave, skillet, or in a simmering sauce on the stovetop.
