In a large pot, bring salted water to a rolling boil. Add rotini pasta and cook according to package instructions for about 10 minutes, until al dente.

Once cooked, drain the pasta and rinse under cold running water to cool it down.

In a large mixing bowl, combine the cooled rotini pasta with cherry tomatoes, cucumber, red onion, black olives, bell pepper, and sharp cheddar cheese.

Drizzle Italian salad dressing over the ingredients and toss everything together until well coated.

Season the salad with salt and pepper to taste, stirring gently.

Cover the bowl and chill the salad in the refrigerator for at least 30 minutes before serving.
