Cook the Pasta: Bring a large pot of salted water to a boil. Add the tri-color pasta and cook according to package directions until al dente. Drain the pasta and rinse it under cold water to cool it down.
Prepare the Veggies: While the pasta is cooling, chop the cherry tomatoes, cucumber, red onion, and slice the black olives.
Combine Ingredients: In a large mixing bowl, combine the cooled pasta, chopped vegetables, mozzarella balls, and sliced olives.
Dress the Salad: Drizzle the Italian dressing over the salad and sprinkle the grated Parmesan cheese on top. Gently toss everything together until well coated.
Season and Serve: Add freshly chopped basil, and season with salt and pepper to taste. Give the salad another gentle toss to incorporate all the flavors.
Chill: For best results, refrigerate the pasta salad for at least 30 minutes before serving to allow the flavors to meld together.
Notes
Serve in a clear glass bowl to showcase the vibrant colors. Garnish with additional basil leaves and a sprinkle of Parmesan before serving.
