In a large bowl, combine the shredded turkey, diced celery, halved grapes, and mixed greens.

In a separate bowl, whisk together the Greek yogurt, honey, lemon juice, salt, and black pepper until smooth.

Pour the dressing over the turkey mixture and toss gently to combine.

Adjust seasoning to taste, adding more salt or pepper if desired.

Serve the salad in bowls, topped with chopped walnuts and fresh parsley.
