Meatball sliders These were extremely easy to make and economical, with the hot dog buns. Make sure that you do spray the foil, as they stick to the foil. I made one batch with (small) provolone slices and one with shredded mozzarella and the mozzarella worked much better. Make sure you do let them sit for 10 minutes after cooking before you try to remove from the pan. Eric and I both felt they needed more marinara sauce on the side to dip them into.
