Add Meatballs: Place the frozen meatballs into the slow cooker.
Prepare Sauce: In a medium mixing bowl, combine the grape jelly, barbecue sauce, and water. Whisk until the mixture is smooth and well blended.
Coat Meatballs: Pour the sauce over the meatballs in the slow cooker, ensuring all the meatballs are thoroughly coated.
Cook:
Set the slow cooker to low heat and cook for 4 to 5 hours, or until the meatballs are heated through and the sauce has thickened.
Alternatively, set the slow cooker to high heat and cook for 2 to 3 hours.
Final Touches: Gently stir the meatballs to evenly distribute the sauce before serving. Garnish with chopped green onions or parsley if desired.
Serve: Serve the meatballs with toothpicks or small serving forks as an appetizer, or enjoy them as a main dish with your favorite sides.
