An American classic, Waldorf salad gets its name from the majestic Waldorf-Astoria Hotel in New York City, where it was first served in 1896. Crunchy, sweet, savory, and satisfying, it is the perfect use for leftover turkey and all those beautiful fruits and nuts from your Thanksgiving table centerpiece. Chopped ripe pears are a great addition; this tasty salad can also be served on a bed of crunchy butter lettuce in place of the celery root.
In a large bowl, gently toss the turkey, celery, celery leaves, apple, grapes, and pecans until combined. In a small bowl, whisk together the yogurt, mayonnaise, honey, and 1/4 teaspoon salt until well combined. Put the celery root in a small bowl, add 2 tablespoons of the dressing, and toss to coat completely. Add the remaining dressing to the turkey mixture, season with salt and pepper, and toss gently to evenly dress the salad.
To serve, spread the celery root evenly onto a serving platter, top with the dressed salad, garnish with celery leaves and serve immediately.
