Crockpot BBQ Meatballs

My mother in law makes a great BBQ meatball appetizer and I wanted to see if I could find a recipe that was similar. This one was really good but I still think hers was better. I paired the meatballs with mac and cheese for dinner tonight as I was really craving comfort food.

Meatballs:
2 lbs lean ground beef or ground turkey
1 cup bread crumbs
1 teaspoon garlic powder
2 envelopes onion soup mix
2 teaspoons Worcestershire sauce
2 eggs

Sauce:
1 cup chopped onion
2 cans tomato paste (12 ounces total)
2 cloves garlic, minced
1/4 cup Worcestershire sauce
3 tablespoons red wine vinegar
1/2 cup brown sugar
12 oz. can beef broth














Combine meatball ingredients and mix well. Shape into meatballs and brown in a skillet with 1 tablespoon of oil. Drain on paper towels. Add all sauce ingredients to Crock Pot and stir well. Add meatballs and cook, covered, on low for 5 to 6 hours (high for 2 to 3).
