Bring a large pot of salted water to a boil. Add the tortellini and cook according to package instructions until al dente, usually about 2-4 minutes for fresh tortellini or 5-7 minutes for frozen. Drain and rinse under cold water to stop the cooking process.
While the tortellini is cooking, prep your vegetables. Halve the cherry tomatoes, dice the cucumber and bell pepper, and finely chop the red onion.
In a large mixing bowl, add the cooled tortellini, cherry tomatoes, cucumber, bell pepper, red onion, and black olives.
Pour the pesto sauce over the mixed ingredients. Toss gently to combine, making sure the tortellini and vegetables are well coated with the pesto.
Add grated Parmesan cheese, and season with salt and pepper to taste. Toss again to distribute the flavors evenly.
For best results, cover the bowl with plastic wrap and refrigerate for at least 30 minutes to allow the flavors to meld together.
Before serving, give the salad a final toss. Garnish with fresh basil leaves for a pop of color and freshness.
Notes
Chill for at least 30 minutes for best flavor.
