Meatball Biscuit Sliders are delicious mini sandwiches made with homemade meatballs, flaky biscuits, and melted cheese. The meatballs are made with a mixture of ground beef, breadcrumbs, Parmesan cheese, and Italian seasoning, and are baked until golden brown. The biscuits are split in half and filled with the meatballs and cheese, and then baked until the cheese is melted and bubbly. These sliders are perfect for parties, game day, or a quick and easy dinner.
