Cook and drain pasta. Cool. Shred onion and pepper. Cut pepperoni, salami, and provolone cheese into 1/2 inch square (approx) cubes.
Mix all cut ingredients together. Add olives then add to pasta. Pour entire bottle of dressing over salad and toss. Sprinkle half of the parmesan cheese onto salad and toss. Sprinkle remaining cheese on top of salad.
Chill for at least an hour. Re-toss pasta salad. If it is dry, add more dressing.
