Ingredients
  

Ingredients
  • 1 lb cheese tortellini (fresh or frozen)
  • 1 cup cherry tomatoes, halved
  • 1 cup cucumber, diced
  • 1/2 cup red onion, finely chopped
  • 1/2 cup black olives, sliced
  • 1/4 cup fresh parsley, chopped
  • 1/4 cup fresh basil, chopped
  • 1/2 cup mayonnaise
  • 1/4 cup sour cream
  • 2 tbsp red wine vinegar
  • 1 tbsp Dijon mustard
  • 1 tsp garlic powder
  • 1 tsp Italian seasoning
  • Salt and pepper to taste
  • 1/4 cup grated Parmesan cheese

Method
 

Instructions
  1. Cook the tortellini: Bring a large pot of salted water to boil. Add the tortellini and cook according to package directions until al dente. Drain well and rinse with cold water to stop the cooking process. Transfer to a large mixing bowl.
  2. Prepare vegetables: While the tortellini cooks, prepare all your vegetables. Halve the cherry tomatoes, dice the cucumber, finely chop the red onion, and slice the black olives. Chop the fresh herbs and set aside.
  3. Make the dressing: In a small bowl, whisk together mayonnaise, sour cream, red wine vinegar, Dijon mustard, garlic powder, Italian seasoning, salt, and pepper until smooth and well combined.
  4. Combine everything: Add the prepared vegetables, herbs, and dressing to the cooled tortellini. Gently toss everything together until well coated. Sprinkle with grated Parmesan cheese and give it one final gentle mix.
  5. Chill and serve: Cover the bowl and refrigerate for at least 1 hour to allow the flavors to meld together. Serve chilled as a main dish or side salad.

Notes

This salad actually tastes better the next day as the flavors have more time to develop. Feel free to add other vegetables like bell peppers, artichoke hearts, or roasted red peppers. For an extra creamy texture, you can use Greek yogurt instead of sour cream.
