Creating Baked Italian Sub Sandwiches is straightforward if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).

2. Prepare the Rolls: Slice the hoagie rolls in half lengthwise. Place the bottom halves on a baking sheet.

3. Layer the Cheese: On each roll, layer 2 oz of provolone cheese on the bottom half.

4. Add the Meats: Evenly distribute the salami, ham, turkey, and pepperoni on top of the cheese.

5. Top with Vegetables: Add the sliced tomatoes, shredded lettuce, and banana peppers to each sandwich.

6. Add More Cheese: Place another layer of provolone cheese over the top of the vegetables.

7. Season the Sandwiches: In a small bowl, whisk together the olive oil, red wine vinegar, Italian seasoning, salt, and pepper. Drizzle this mixture over the assembled sandwiches.

8. Cover with Top Halves: Place the top halves of the rolls over the fillings.

9. Wrap and Bake: Wrap the sandwiches in aluminum foil and place them in the oven. Bake for 15-20 minutes, or until the cheese is melted and the rolls are toasted.

10. Serve: Carefully unwrap the sandwiches from the foil. Slice them in half and serve warm.

These steps will guide you in creating these incredible sandwiches effortlessly.
