Step 1

Preheat the oven to 375°F. Leaving the buns attached together, slice them open with a long knife. You should have two rectangle sheets, the top and bottom half.

Step 2

Place the bottom half on a baking pan with edges. Spread on the marinara sauce on the bottom layer of buns, layer on the pepperoni, shredded cheese, and any other topping you prefer. Replace the top layer of buns.

Step 3

Melt the butter and stir in the Parmesan, garlic powder, and oregano. Pour the butter and cheese mixture over the top of the buns.

Step 4

Bake for 12 minutes or until the cheese is melted. If the tops brown before they are ready cover lightly with aluminum foil and continue to bake.

Step 5

Remove from the oven. Slice the rolls apart and serve warm.
