Ingredients
  

Ingredients
  • 1 lb cheese tortellini (fresh or frozen)
  • 1 cup cherry tomatoes, halved
  • 1/2 cup black olives, sliced
  • 1/2 cup green olives, sliced
  • 1/2 cup red onion, finely diced
  • 1/2 cup bell peppers, diced (any color)
  • 1/4 cup fresh parsley, chopped
  • 1/4 cup fresh basil, chopped
  • 1 cup mayonnaise
  • 1/4 cup sour cream
  • 2 tablespoons apple cider vinegar
  • 1 teaspoon Italian seasoning
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • Salt and pepper to taste
  • 1/4 cup grated Parmesan cheese

Method
 

Instructions
  1. Cook the tortellini according to package directions. Drain well and rinse with cold water to stop the cooking process. Allow to cool completely.
  2. While the tortellini cools, prepare your vegetables. Halve the cherry tomatoes, slice the olives, dice the red onion and bell peppers, and chop the fresh herbs.
  3. In a large mixing bowl, whisk together the mayonnaise, sour cream, apple cider vinegar, Italian seasoning, garlic powder, onion powder, salt, and pepper until smooth and well combined.
  4. Add the cooled tortellini to the dressing and gently toss to coat. Fold in the prepared vegetables, olives, and fresh herbs.
  5. Sprinkle with grated Parmesan cheese and gently mix one more time. Cover and refrigerate for at least 1 hour to allow the flavors to meld together.
  6. Before serving, give the salad a good stir and adjust seasoning if needed. Garnish with additional fresh herbs if desired.

Notes

For best results, make this salad at least 2-3 hours ahead of time. The flavors develop beautifully as it chills. If making for a party, prepare it the night before but add fresh herbs right before serving to keep them vibrant. Recipe is versatile - try adding cucumbers, artichoke hearts, or grilled chicken.
