Prepare one 12-oz package tri-colored rotini pasta as directed on the package. Drain and cool. Add one cup of diced cooked ham, ½ green bell pepper diced, ½ thinly sliced red onion, ¼ cup sliced black olives, and ½ cup shredded or small mozzarella balls. Toss well with our Italian Balsamic Vinaigrette. Great salad for special gatherings.
