Quick Italian Pasta Salad

1 (12 ounce) package tri-color rotini pasta

¾ pound Italian salami, finely diced

½ green bell pepper, sliced

½ red bell pepper, sliced

½ red onion, chopped

1 cup Italian-style salad dressing

1 (6 ounce) can sliced black olives

8 ounces small fresh mozzarella balls (ciliegine)

3 (.7 ounce) packages dry Italian-style salad dressing mix, or to taste

½ cup shredded Parmesan cheese

Bring a large pot of lightly salted water to a boil; cook rotini at a boil until tender yet firm to the bite, about 8 minutes; drain and rinse with cold water until cool.

Combine pasta, salami, green bell pepper, red bell pepper, onion, salad dressing, olives, and mozzarella cheese in a large bowl. Mix dry salad dressing into pasta; sprinkle with Parmesan cheese.
