Ingredients

1/2 cup grated Parmesan cheese
3 tablespoons extra-virgin olive oil
2 teaspoons apple cider vinegar
2 tablespoons unsalted butter , melted
1 clove garlic , minced
1 teaspoon dried oregano
1/4 teaspoon cracked red pepper flakes
1 package (12 count) sweet Hawaiian rolls
1 cup marinara sauce , divided
2 cups shredded mozzarella cheese , divided
14 ounce jar marinated artichoke hearts , drained and chopped
1 small green bell pepper , seeded and diced very small
4 ounces sliced pepperoni
2.25 ounce can sliced black olives , drained

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.
