Follow these simple steps to create your Tortellini Pasta Salad with Prosciutto:

1. Cook the Tortellini: In a large pot of boiling salted water, cook the tortellini according to package instructions. Drain and rinse under cold water to stop the cooking process. Set aside.
2. Prepare the Dressing: In a small bowl, whisk together the olive oil, red wine vinegar, Dijon mustard, salt, and pepper to taste. Adjust according to preference.
3. Mix the Salad Ingredients: In a large mixing bowl, combine the cooked tortellini, prosciutto, cherry tomatoes, cucumber, bell pepper, red onion, parmesan cheese, and fresh basil.
4. Add the Dressing: Pour the dressing over the salad mixture and toss gently to combine all the ingredients evenly. Ensure the salad is well-coated with the dressing.
5. Chill: If time allows, cover the bowl with plastic wrap and let it sit in the refrigerator for at least 10 minutes to allow the flavors to meld.
6. Serving Option: If desired, garnish with more fresh basil or parmesan cheese before serving.
