Bring a pot of salted water to a boil and cook the tortellini according to package instructions until al dente. Drain and rinse under cold water to stop the cooking process.
In a large mixing bowl, combine the halved cherry tomatoes, diced cucumber, diced bell pepper, chopped red onion, and sliced black olives.
Add the cooked tortellini to the vegetable mixture and gently toss to combine.
Drizzle the Italian dressing over the salad and sprinkle with chopped basil, salt, and pepper. Toss everything together until well coated with the dressing.
Let the salad sit in the refrigerator for at least 30 minutes to allow the flavors to meld together.
Before serving, give the salad a final toss and garnish with grated Parmesan cheese.
Notes
