These 3-ingredient savory-sweet grape jelly meatballs are easily made in your slow cooker for the perfect party recipe that will go quickly at any gathering!
Pour the sauce ingredients over the meatballs, then toss with 2 spoons until coated.
Cook for 2-3 hours on high or 4-6 hours on low. The sauce will thicken more as it cools a bit. Use the "keep warm" setting if you're not going to be eating them right away.
Notes
If you're serving this as an appetizer, it serves 8+, but it really depends what else it's served with and how much people eat. If you want to serve it as a main course (like with rice or mashed potatoes, it'll serve 4).
Frozen meatball package sizes vary. If yours is larger, add a bit more of the chili sauce and grape jelly (like up to 1.5 or 2 cups each).
I used ketchup in the nutrition info since my database doesn't have Heinz chili sauce. It's similar in calories, so it gives you a ballpark figure.
