Spread lettuce on the tortilla, leaving about 1 inch of the edge on the round sides.
Place the tomato slices across the lettuce aligned from one straight edge to the other.
Mix oil, vinegar, oregano, salt, pepper, crushed red pepper flakes, and parmesan cheese in a small bowl, and brush this Italian dressing on the tomato slices.
Layer the rest of the ingredients on the tomato in this order: provolone cheese, salami, ham, pepperoncini slices.
Carefully roll it up and cut in half. Enjoy!
