Preheat the oven to 325° and grease the bottom of a 9x13 baking dish.
Bake a bag of Rhodes Warm-N-Serv rolls for 10 minutes. Carefully cut the rolls in half and place the bottom halves in the greased baking dish.
Spread sauce over the roll halves in the pan. Top with 1 c. mozzarella cheese, pepperoni slices, and top with remaining 1 c. mozzarella cheese. Cover each slider with the top halves.
Use a pastry brush to brush the butter mixture onto each slider. Cover with aluminum foil and bake for 20 minutes, or until cheese is melted. Serve and enjoy!
