Creating this delicious Creamy Chicken Pasta Salad is remarkably simple. Just follow these easy steps:

1. Cook the Pasta: Begin by boiling a pot of salted water. Add the pasta and cook according to package instructions until al dente. Drain and rinse under cold water to stop the cooking process.
2. Prepare the Chicken: If using raw chicken, season it with salt and pepper. Cook in a skillet over medium heat for about 6-7 minutes or until fully cooked. Dice it into bite-sized pieces.
3. Chop the Vegetables: While the pasta cools, chop the cherry tomatoes, cucumber, red bell pepper, and green onions. Set them aside in a large bowl.
4. Make the Dressing: In a separate bowl, combine the mayonnaise, Greek yogurt, Dijon mustard, lemon juice, salt, and pepper. Whisk until smooth and creamy.
5. Combine Ingredients: In the bowl with the chopped vegetables, add the cooled pasta and diced chicken. Pour the dressing over the top and mix gently until everything is well coated.
6. Chill the Salad: Cover the bowl and refrigerate for at least 30 minutes. This allows flavors to blend beautifully.
7. Serve: Before serving, give the salad a light toss again and adjust seasoning if needed. Garnish with fresh parsley if desired.
