Creating Mediterranean Chicken Pasta Salad is easier than you might think! Follow these simple steps to assemble this delicious dish:

1. Cook the Pasta: In a large pot of salted boiling water, cook the rotini pasta according to package instructions until al dente. Drain and rinse under cold water to cool.

2. Prepare the Chicken: While the pasta is cooking, season the chicken breasts with olive oil, garlic powder, Italian seasoning, salt, and pepper.

3. Cook the Chicken: In a large skillet over medium heat, cook the seasoned chicken for about 6-7 minutes per side, or until fully cooked. Make sure the internal temperature reaches 165°F (75°C). Remove from heat and allow to rest.

4. Chop Ingredients: While the chicken is resting, prepare other salad ingredients. Chop the cherry tomatoes, cucumber, red onion, and parsley.

5. Slice the Chicken: Once cooled, slice the cooked chicken into bite-sized pieces.

6. Make the Dressing: In a small bowl, whisk together lemon juice, olive oil, Dijon mustard, and dried oregano until well combined.

7. Combine the Ingredients: In a large bowl, combine the cooked pasta, sliced chicken, chopped tomatoes, cucumber, red onion, black olives, feta cheese, and parsley.

8. Add the Dressing: Pour the dressing over the salad ingredients and gently toss until everything is well coated.

9. Chill the Salad: For enhanced flavor, cover the salad and chill in the refrigerator for about 15-20 minutes before serving.

10. Serve: Once chilled, give the salad another light toss, then serve it in bowls or on a platter.
