Delish Meatballs

I got this recipe from a friend. It's to die for! I promise. I'd take a picture, but my camera is MIA. Not a happy mom right now!

Sweet and Sour Meatballs
1 bag (80 ct) frozen home style meatballs (other flavors work fine too)
1 c. Ketchup
1 c. brown sugar
2 tsp liquid smoke (you can find this by the BBQ sauce)
1 tsp. garlic powder
2-4 Tbs apple cider vinegar
2 cups cooked rice

Place frozen meatballs in a baking dish. Mix ketchup, b. sugar, liquid smoke, garlic powder, and vinegar. Pour over meatballs and stir to coat. Cover and bake at 350 degrees for 30 minutes. Serve over rice.
