Add meatballs and cook on low for at least 3-4 hours. Stir occasionally to keep the sauce blended over the meatballs.
**NOTE: The 4 lb bag will have about 123 meatballs and can be purchased at Walmart. This recipe is also easy to modify. If you only need a smaller portion, use a 2 lb bag (or half the large bag) and only add one jar of the sauce and one jar of grape jelly.
