Begin by assembling all necessary ingredients.

Fill a large pot with lightly salted water and bring it to a boil. Add the tri-color rotini pasta and cook until al dente, approximately 8 minutes. Once cooked, drain the pasta and rinse it under cold water until it has cooled down.

In a spacious bowl, combine the cooked pasta, diced salami, sliced bell peppers, chopped onion, mozzarella balls, and black olives. Pour in the Italian-style salad dressing and toss everything together to ensure even coating.

Adjust the flavor by mixing in the dry Italian-style salad dressing mix, stirring until well incorporated.

Before serving, generously sprinkle the salad with shredded Parmesan cheese. Enjoy!
