Making your Italian Grinder Sandwich is easy when you follow these steps:

1. Prep the Roll: Slice your Italian hoagie roll in half horizontally but don’t cut all the way through. Leave it hinged.

2. Layer the Meats: Start by layering salami, capicola, and mortadella on the bottom half of the roll.

3. Add Cheese: Place the provolone cheese slices atop the meats for a deliciously creamy texture.

4. Load with Vegetables: Add shredded lettuce and tomato slices for freshness. Sprinkle sliced banana peppers for a tangy kick.

5. Drizzle Olive Oil: Drizzle a light amount of olive oil over the sandwich, enhancing flavor and moisture.

6. Add Red Wine Vinegar: Drizzle red wine vinegar over the ingredients to give a zesty flavor.

7. Season: Sprinkle Italian seasoning, salt, and pepper to taste for an added layer of flavor.

8. Close the Roll: Gently close the sandwich and press down slightly to meld all the ingredients together.

9. Optional Toasting: You can toast the sandwich in a pan or sandwich press if you prefer a warm version.

10. Slice and Serve: Finally, cut the sandwich into halves or quarters for easy serving.

By adhering to these steps, you’ll prepare an authentic Italian Grinder Sandwich that bursts with flavors.
