Cook the pasta according to the package directions until al dente. Do not add salt to the water since the dressing already has plenty of flavor. Drain the pasta and rinse it under cold water to cool it down.
Add the cooled pasta to a large bowl. Add the halved tomatoes, chopped broccoli, bell pepper, olives, cucumber, carrots, red onion, and parmesan cheese.
Pour the Italian dressing over everything. Toss gently until all the ingredients are evenly coated.
Cover the bowl and chill in the refrigerator for at least 30 minutes, or up to 1 day.
Before serving, give the salad a good toss. Add a little more dressing if needed so it stays fresh and flavorful.
