Instructions
Preheat the oven to 350 degrees F. Spray a 9×13-inch baking dish with nonstick cooking spray.
In a small bowl, whisk together the grated Parmesan, olive oil, vinegar, butter, garlic, oregano, and red pepper flakes.
Do not pull the rolls apart. Instead, using a large serrated knife, slice the rolls in half (like you would a bagel) so you have a top and bottom "slab."
Place the bottom layer into the prepared baking pan, cut side up, then spread with half of the marinara sauce.
Top with 1 cup of the mozzarella cheese, artichoke hearts, bell pepper, pepperoni, olives, and finish with the remaining 1 cup shredded cheese.
Spread the remaining marinara sauce on the cut side of the top slab of rolls and place onto the sandwiches.
Slowly and evenly pour the oil/butter mixture over the rolls. Let stand for 5 minutes.
Cover the pan with foil. Bake for 18-20 minutes.
Remove the foil from the baking pan, return the sliders to the oven and bake uncovered for an additional 5 minutes until rolls are golden.
Let rest for 5 or so minutes, then cut into individual sandwiches and serve immediately.
