Nutrition is based on a 64 count bag of 1/2-ounce frozen meatballs and assumes all the sauce will be consumed.Make this recipe in a crockpot:For this recipe, a crockpot is used to keep them warm for your party, but you could cook them in there too if you have the time. Mix the sauce ingredients in the crock pot, then pour in the bag of meatballs. Stir to coat the meatballs in the sauce, and cook on LOW for about 4 hours. Be sure to stir every hour so the meatballs stay covered in the sauce and don't burn on the bottom.
