01 - Season chicken breasts with salt and pepper. Heat olive oil in a skillet over medium heat. Cook chicken for 7 to 8 minutes per side, or until fully cooked and juices run clear. Remove from heat and let rest for 5 minutes, then dice or shred into bite-sized pieces.
02 - In a large bowl, combine diced chicken, celery, red onion, apple, grapes, nuts, and cilantro or parsley.
03 - In a separate small bowl, whisk together mayonnaise, Greek yogurt, mango chutney, curry powder, turmeric, ground cumin, lemon juice, honey, salt, and black pepper until smooth and well blended.
04 - Pour the dressing over the chicken mixture. Toss gently to coat everything evenly.
05 - Taste and adjust seasoning, adding more salt, pepper, or lemon juice as needed.
06 - Cover and refrigerate at least 30 minutes before serving to allow flavors to meld.
07 - Serve chilled as a salad, in sandwiches, wraps, or on a bed of greens.
