BBQ Meatball Sliders 1 pound ground beef 1/2 cup bread crumbs 1/2 cup shredded cheese 1 egg 1/3 pound bacon, chopped 1 medium onion, chopped 1/4 cup BBQ sauce 3 slices cheddar cheese 12 Rolls Preheat oven to 375 degrees F and line a lipped baking sheet with parchment paper and non-stick spray. Combine the bread crumbs, shredded cheese, ground beef and egg until evenly distributed. Roll the mixture into 1-1/2 to 2 inch meatballs and space evenly on the baking sheet. Bake for 30 minutes. While the meatballs are baking, fry the bacon until crispy over medium-high heat. Remove bacon from skillet, leaving the grease in the skillet. Add the onions to the skillet and reduce heat to medium, stirring often until tender. Cut rolls in half and add one meatball to the bottom portion of each roll. Brush the tops with BBQ sauce. On top of the meatballs add the cheese slices, bacon bits and grilled onions. Place under the broiler next to the roll tops for 2-3 minutes until cheese is melted. Top the meatballs with the rolls and serve.
