Cook the tri-color rotini pasta according to the package instructions until it's al dente. Avoid adding salt to the water.

Once cooked, drain the pasta and rinse it under cold water.

In a large mixing bowl, combine the cooled pasta, halved tomatoes, chopped broccoli, bell pepper, sliced olives, diced cucumber, sliced carrots, chopped red onion, and shredded parmesan cheese.

Pour the Italian salad dressing over the ingredients in the bowl and toss everything together until it is evenly coated.

Cover the bowl and chill the pasta salad in the refrigerator for at least 30 minutes or up to 1 day. If needed, add a little more dressing before serving.
