Bring a large pot of salted water to a boil. Add the rotini pasta and cook for 7 minutes, stirring occasionally.

Drain the water and set the pasta aside to cool for 10 minutes.

In a large bowl, combine the cooled pasta, cherry tomatoes, and diced cucumber.

Add the red onion, black olives, green bell pepper, yellow bell pepper, pimento peppers, parsley, pepperoni, and salami.

Cube the mozzarella cheese and add it to the bowl.

Pour the Italian dressing over the salad and mix thoroughly until all ingredients are well combined and coated.

Add salt to taste. Serve the pasta salad immediately or chill in the refrigerator for later.
