Creating the perfect Italian Grinder Sandwich involves a few straightforward steps. Follow these instructions for a delightful outcome:

1. Prepare the Bread: Start by slicing the Italian bread or hoagie rolls in half lengthwise. If desired, hollow out some of the inner bread to create extra room for fillings.

2. Layer the Meats: Begin layering the sandwich by placing the salami on the bottom half of the bread. Stack the ham and then the capicola, allowing the meats to cover the bread evenly.

3. Add the Cheese: Place slices of provolone cheese generously over the meats to amp up the flavor profile.

4. Top with Vegetables: Add the shredded lettuce, tomato slices, red onion, roasted red peppers, and black olives. Ensure the toppings are evenly distributed.

5. Seasoning: Sprinkle the dried oregano evenly over the vegetable layer. Season with salt and pepper to taste.

6. Make the Dressing: In a small bowl, whisk together the red wine vinegar and olive oil. Drizzle the dressing evenly over the toppings on the sandwich.

7. Assemble the Sandwich: Carefully place the top half of the bread back onto the sandwich.

8. Heat it Up: If you prefer, wrap the sandwich in foil and place it in a preheated oven at 350°F (175°C) for about 10 minutes, or until the bread is toasted and the cheese starts to melt.

9. Slice and Serve: Once heated through, take the sandwich out of the oven, unwrap, and slice it into portions.

These steps will help you craft a delicious Italian Grinder Sandwich with layers of flavors and textures that are hard to resist.
