Cook the rotini pasta according to the package instructions. Drain the pasta and allow it to cool completely.

Combine the cooled pasta in a large bowl with chopped cucumber, halved grape tomatoes, chopped carrots, sliced red onion, and chopped yellow bell pepper.

Add the grated parmesan cheese and cubed mozzarella cheese to the bowl, ensuring they are evenly distributed.

Sprinkle in the McCormick Salad Supreme Seasoning and toss everything together until well-coated and combined.

Pour the zesty Italian dressing over the salad and mix until all ingredients are well-coated.

Chill in the refrigerator for at least 1 hour before serving.
