Begin by preparing your ingredients: shred or chop the rotisserie chicken, chop the dill pickles, chop the celery, and mince the fresh dill.

In a large mixing bowl, combine the Greek yogurt, mayonnaise, grainy mustard, Dijon mustard, and the zest and juice of the lemon. Whisk until smooth.

Add the prepared chicken, chopped dill pickles, celery, and fresh dill to the bowl. Toss gently until evenly coated with the dressing.

Taste and season the salad with salt as needed, mixing again to enhance the flavor.

For the best flavor, cover and refrigerate for about 15 minutes before serving.
