Mix and match your toppings, top with a generous amount of mozzarella cheese, brush with butter, then bake until golden. That's really all there is to it!
Preheat oven to 350F and grease a 13x9 baking dish.
Melt the butter in a saucepan over medium heat or in the microwave.
Slice the buns across the middle and set the tops to the side.
Spread the pizza sauce over the bottom sections of the buns and place into the baking dish.
Spread 1 cup of mozzarella cheese over the top of the sauce.
Layer the pepperoni slices to make one full layer over the top of the cheese.
Sprinkle with remaining 1 cup mozzarella cheese.
Place tops of rolls back on and baste with melted butter.
Sprinkle on oregano or Italian seasoning and cover with aluminum foil.
Bake sandwiches for 20 minutes until cheese is melted and butter has been fully absorbed, resulting in golden sandwich tops.

Notes
We're partial to homemade pizza sauce around here, but any store-bought sauce will do the trick if you want to save a little extra time.
Both shredded or sliced mozzarella cheese work for this recipe. Shredding the cheese straight from the block is your best bet to make it extra melty and delicious.
Instead of pepperoni, or in addition to, you can easily use pizza sausage. Green peppers, mushrooms, onions, olives, or just about any of your favorite pizza toppings can also be incorporated! If you plan on adding vegetables I would recommend quickly sauteeing them before adding them to the sliders to be sure they are cooked through when coming out of the oven. The same goes for the sausage, crumble and cook partially before adding to ensure doneness.
