• Slice the rolls in half the long way into sandwiches. Use cooking spray to lightly oil the baking dish. Place the bottom half on a lightly oiled baking dish and set aside the top half.
• Spread the tomato paste over the bottom half of the rolls evenly.
• Mix together the Italian seasoning, onion powder and salt. Spread half of the spices evenly across the tomato paste, saving the rest for the top.
• Add the pepperoni evenly over the tomato paste and seasoning. Sprinkle the mozzarella over the pepperoni.
• Place the top half of the rolls on top and gently press down.
• Mix the melted butter and garlic together, then brush the butter mixture over the top of the rolls.
• Sprinkle remaining Italian Seasoning and onion powder evenly across the butter spread.

For The Oven

• Preheat the oven to 350-degrees.
• Cover with foil and place in the oven and bake for 20 minutes. Remove the foil and cook for an additional 2-3 minutes or until golden brown. Garnish with parmesan cheese and parsely if desired.

For The Air Fryer

• Place the sliders in your air fryer in a single layer. Heat the air fryer to 350 degrees.
• Cook the sliders for 4-6 minutes uncovered, or until a light golden brown. Work in batches if your air fryer isn't big enough to place all the sliders in at once. Garnish with parmesan cheese and parsley if desired.
