A bright, creamy chicken pasta salad loaded with rotini, juicy tomatoes, crisp cucumber, olives, and feta, all tossed in a zesty lemon–Dijon dressing. Perfect for make-ahead lunches, potlucks, or a light weeknight dinner.
Cook the rotini in a large pot of salted boiling water until al dente, about 8 to 10 minutes. Drain and rinse under cold water to cool completely, then shake off excess water.
In a mixing bowl, whisk together mayonnaise, Greek yogurt, olive oil, lemon juice, Dijon, honey, garlic powder, salt, black pepper, and oregano until smooth.
In a large bowl, combine cooled pasta, chicken, cherry tomatoes, cucumber, red onion, bell pepper, olives, parsley, and feta.
Pour the dressing over the salad and toss gently until everything is evenly coated. Adjust seasoning with additional salt, pepper, or lemon juice to taste. Add red pepper flakes if using.
Cover and chill for 30 minutes to let the flavors meld. Toss again before serving.
Notes
For best texture, rinse the pasta to stop cooking and cool it quickly. This salad holds well for up to 3 days in the refrigerator; if making ahead, reserve a little dressing to refresh before serving.
