Preheat your oven to 375°F (190°C). Line a large baking sheet with parchment paper or foil. Slice each hoagie roll horizontally, leaving a hinge so it opens like a book. Lightly spread the inside of each roll with softened butter or mayonnaise.
4 hoagie rolls or grinder rolls, 2–3 tbsp butter or mayonnaise
Lay 1–2 slices of provolone on the bottom side of each roll. Layer the deli meats over the cheese in your preferred order (such as salami, ham, turkey or capicola, and pepperoni), folding the slices slightly for a stacked texture. Top with another slice of cheese if desired, then sprinkle with Italian seasoning, salt, and black pepper.
8 slices provolone cheese, 6 oz sliced salami, 6 oz sliced ham, 6 oz sliced turkey or capicola, 4–6 slices pepperoni, 1–2 tsp Italian seasoning, salt and black pepper
Arrange the filled rolls open-faced on the prepared baking sheet, meat and cheese side up. Bake for 8–12 minutes, or until the cheese is melted and bubbling and the rolls are lightly golden. For extra toasty tops, switch to broil for 1–2 minutes at the end, watching carefully so they don’t burn.
While the sandwiches bake, whisk together the mayonnaise, red wine vinegar, olive oil, Dijon mustard, dried oregano, garlic powder, onion powder, crushed red pepper flakes (if using), and grated Parmesan in a medium bowl. Season to taste with salt and pepper; the dressing should be tangy, creamy, and well-seasoned.
3/4 cup mayonnaise, 2 tbsp red wine vinegar, 1 tbsp olive oil, 1 tsp Dijon mustard, 1 tsp dried oregano, 1/2 tsp garlic powder, 1/2 tsp onion powder, 1/4–1/2 tsp crushed red pepper flakes, 2–3 tbsp grated Parmesan cheese, salt and pepper
In a large bowl, combine the shredded iceberg lettuce, shredded Romaine (if using), tomatoes, sliced red onion, and banana peppers or pepperoncini. Spoon the dressing over the vegetables and toss until everything is evenly coated. Let the salad sit for 5–10 minutes to allow the flavors to meld and the onions to soften slightly.
2 cups shredded iceberg lettuce, 1 cup shredded Romaine lettuce, 1 cup cherry or grape tomatoes, 1/2 small red onion, 1/2 cup banana peppers or pepperoncini
Remove the sandwiches from the oven and let cool for 1–2 minutes. Pile a generous amount of grinder salad on top of the hot meat and cheese in each roll, then gently close the sandwiches, pressing lightly so the fillings settle together. Slice each sandwich in half on a diagonal and serve immediately while the bread is warm and the salad is crisp.
