Cook 16 oz rotini pasta according to package directions until al dente.
Drain, and rinse with cold water. Set aside.
In a large bowl, combine the cooked pasta, 2 cups cherry tomatoes (halved), ½ pound mozzarella cheese (cubed), 4 oz pepperoni (cut in half), 1 diced green bell pepper, and 1 can (6 oz) black olives (drained).
Pour 8 oz Italian dressing over the pasta mixture and toss until evenly coated. Stir in 6 oz shredded parmesan cheese and mix well.
Let sit in the refrigerator for at least one hour for the flavors to come together.
