Creating Hot Italian Sub Sliders is a straightforward process. Follow these simple steps to whip up these delectable sandwiches:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Prepare a baking dish or sheet pan by lightly greasing it.
2. Prepare the Rolls: Slice the slider rolls in half horizontally while keeping them connected. Place the bottom halves in the prepared baking dish.
3. Layer the Meats: Evenly layer the salami, pepperoni, and ham over the bottom halves of the rolls.
4. Add Cheese: Place the provolone cheese slices over the meats, followed by a generous sprinkle of shredded mozzarella cheese.
5. Cover with Roll Tops: Place the tops of the rolls on the cheese, forming sliders.
6. Make the Topping: In a small bowl, combine the melted butter, Italian seasoning, garlic powder, and crushed red pepper flakes, if using.
7. Brush the Sliders: Brush the melted butter mixture generously over the tops of the slider rolls.
8. Bake: Cover the baking dish with aluminum foil and bake in the preheated oven for 15-20 minutes. Remove the foil and bake for an additional 10 minutes or until the cheese is gooey and the rolls are lightly golden.
9. Rest Before Serving: Allow the sliders to cool for about 5-10 minutes before slicing them into individual pieces. This helps the cheese set slightly, making them easier to handle.
10. Garnish and Serve: If desired, sprinkle chopped fresh basil over the top. Serve with warm marinara sauce for dipping.
