Bring a large pot of salted water to a boil. Add the rotini pasta and cook according to package instructions until al dente. Drain and rinse under cold water to cool.

In a large mixing bowl, combine the cooled pasta, cherry tomatoes, cucumber, bell pepper, and black olives.

Pour the Italian dressing over the pasta and vegetables. Toss gently to combine.

Sprinkle with chopped parsley and basil. Serve immediately or refrigerate for 30 minutes to allow flavors to meld.
