Step 1: In a large mixing bowl, combine the Greek yogurt, Dijon mustard, and honey. Mix them well to create a creamy dressing base.
Step 2: Add the shredded chicken to the dressing and toss until the chicken is thoroughly coated.
Step 3: Now, add the diced celery, red onion, halved grapes, diced apple, and chopped parsley to the chicken mixture. Gently fold the ingredients together until they are evenly distributed.
Step 4: If desired, add chopped walnuts or almonds for extra crunch and flavor.
Step 5: Season the salad with salt and pepper to taste. Adjust the seasoning according to your preference.
Step 6: Once the salad is well combined, cover the bowl and refrigerate it for at least 15-20 minutes to allow the flavors to meld.
Step 7: Before serving, line a plate or bowl with fresh lettuce leaves or mixed greens. Scoop the chilled chicken salad onto the greens.
Step 8: Enjoy your delicious and nutritious low-calorie chicken salad!
