Preheat the oven to 350 degrees F. Using a 8x8 or 8x10 baking dish, use butter to grease the bottom so the rolls don't stick.

Assemble the sliders: Place the bottom half of the buns into the baking dish, then spread mayonnaise over the top, add cheese slices, sliced turkey pieces, cranberry sauce, and the top of the buns. Rub some butter over the tops of the buns and then sprinkle parmesan cheese over the top.

Cover the baking dish loosely with aluminum foil. Place into the oven and bake for 20 minutes. Remove the foil and bake 5 additional minutes. Carefully remove from the oven and set aside.

Using a serrated knife, cut the sliders into individual sandwiches and serve immediately!
