Add the frozen meatballs, grape jelly, barbecue sauce, and chili garlic sauce directly into your slow cooker. Stir everything together until the meatballs are evenly coated with the sauce mixture.

Cover the slow cooker with its lid and cook on the low setting for 3-4 hours. If you're using larger meatballs, they may need 4-5 hours on low to become perfectly tender. Give everything a gentle stir about halfway through cooking time.

Once the meatballs are heated through and the sauce has thickened, switch your slow cooker to the warm setting until you're ready to serve. Before serving, give everything a final stir and transfer to a serving dish or keep in the slow cooker for guests to help themselves. Sprinkle with chopped parsley or chives if desired.
