Creating your Italian Grinder Salad Sandwich is simple when you follow these easy steps:

1. Prepare the Dressing: In a small bowl, whisk together olive oil, red wine vinegar, Italian seasoning, salt, and pepper.
2. Slice the Bread: Cut the hoagie roll lengthwise, not entirely through, to create a pocket for the filling.
3. Layer the Meats: Start by placing the sliced salami evenly in the bottom half of the roll.
4. Add the Ham: Layer the sliced ham on top of the salami.
5. Top with Cheese: Place the provolone cheese over the meats for a rich, creamy texture.
6. Add Vegetables: Evenly distribute the shredded lettuce, sliced tomatoes, red onions, and pepperoncini peppers on top of the cheese.
7. Drizzle Dressing: Spoon the prepared dressing over the vegetables, ensuring even coverage.
8. Finish Assembling: If using olives, sprinkle them on top before closing the sandwich.
9. Press and Slice: Gently press the top half of the roll down, sealing the sandwich. Slice into manageable sections for serving.
10. Serve: Enjoy your delicious Italian Grinder Salad Sandwich immediately or wrap it up for later.

These steps will guide you in making this delightful and satisfying sandwich with minimal fuss.
