In this easy meatball appetizer, meatballs are tossed in sweet BBQ sauce before being topped with cheddar cheese, sautéed onions, and crispy bacon! To finish off these meatball sliders, they're then sandwiched between sweet Hawaiian rolls.
If using frozen meatballs, place meatballs in medium saucepan with BBQ sauce. Place over medium heat to heat through (about 15-20 minutes). If using homemade meatballs, toss cooked meatballs in BBQ sauce. Set aside.
