How to Make It
Preheat oven to 400˚F. Place a wire rack in a rimmed baking sheet. Spray wire rack with non-stick cooking spray.
Mix sirloin and next 7 ingredients thoroughly (using hands works best) and shape into 15-20 (2-ounce) balls. Arrange meatballs on the wire rack. Bake for 24-26 minutes, or until internal temperature is 165˚F.
Transfer half of Coca-Cola Barbecue Sauce to Dutch oven over low-heat. Add meatballs and keep warm to serve. Serve each meatball on a slider bun with pickles, sliced sweet onions, and extra sauce.
