- Prepare The Chicken: Begin by poaching or grilling the chicken breasts until they are fully cooked. Allow them to cool, then dice them into bite-sized pieces. 
- Chop The Vegetables And Fruits: Finely chop the celery and red onion. Halve the grapes, dice the apple, and chop the toasted pecans. 
- Combine The Ingredients: Combine the diced chicken, chopped celery, red onion, grapes, diced apple, toasted pecans, and dried cranberries in a large mixing bowl. Gently toss everything together to distribute the ingredients evenly. 
- Prepare The Dressing: Whisk together the mayonnaise, Greek yogurt, honey, Dijon mustard, fresh lemon juice, salt, and pepper in a separate bowl. Taste and adjust the seasoning as needed to achieve the desired balance of flavors. 
- Combine The Salad And Dressing: Pour the dressing over the chicken and vegetable mixture. Gently fold the sauce into the salad until everything is well coated. 
- Chill And Serve: Cover the chicken salad and refrigerate for at least 30 minutes to allow the flavors to meld. When ready to serve, garnish with additional chopped pecans and a few fresh herbs if desired.
