Cook the Pasta: Begin by boiling water in a large pot. Add the rotini or penne pasta and cook according to the package instructions until al dente, which typically takes about 8-10 minutes. Drain the pasta and rinse it under cold water to halt the cooking process.

Chop the Veggies: While the pasta is cooling, take the time to chop your cherry tomatoes, cucumber, and bell pepper into small, bite-sized pieces.

Combine Ingredients: In a large mixing bowl, combine the cooled pasta, chopped tomatoes, diced cucumber, chopped bell pepper, and sliced black olives. Toss gently.

Add Dressing and Cheese: Drizzle the Italian dressing over the pasta and veggies. Then, add the freshly grated Parmesan cheese on top. Toss again until all the ingredients are beautifully coated.

Chill Before Serving: Cover the bowl and place it in the refrigerator to chill for at least an hour.
