Making your own Italian Grinder Sandwich is straightforward and fun. Follow these steps:

1. Prepare the Roll: Slice the Italian sub roll in half lengthwise. Optionally, you may choose to toast it slightly for added texture.
2. Layer Meats: Begin by layering the genoa salami evenly on the bottom half of the roll. Follow with the pepperoni and capicola.
3. Add Cheese: Place slices of provolone cheese on top of the meats.
4. Fresh Vegetables: Next, layer on the shredded lettuce, sliced tomato, and red onion. Add banana peppers and black olives if you like an extra kick.
5. Drizzle Dressing: In a small bowl, whisk together olive oil, red wine vinegar, salt, pepper, oregano, and Italian seasoning. Drizzle this mixture over the sandwich filling for added flavor.
6. Complete the Sandwich: Top with the other half of the roll, gently pressing down to compact the ingredients.
7. Slice and Serve: Cut the sandwich in half or into smaller portions, depending on your preference.
8. Optional Toasting: If desired, you may return the sandwich to a hot skillet to toast both sides for a crispy experience.

By following these steps, you’ll create a delicious Italian Grinder Sandwich that is irresistible!
