Slice each sub roll lengthwise without cutting all the way through

In a small bowl, whisk together extra virgin olive oil, red wine vinegar, dried oregano, garlic powder, black pepper, and salt to make the Italian dressing

Layer the bottom of each roll with Genoa salami, capicola (or ham), provolone cheese, and turkey breast

Add shredded lettuce, tomato slices, red onion, pepperoncini, and roasted red peppers over the meats and cheese

Drizzle the prepared Italian dressing generously over the sandwich fillings

If using, add fresh basil leaves for extra herbaceous brightness

Close the sandwiches gently, press slightly, and serve immediately
