First, you want to chop up the turkey into small pieces. You can leave the skin if you'd like.
Next, in a small bowl whip together the ingredients for the salad dressing. Then, mince the celery.
Now, combine the dressing, celery, relish and the chopped turkey. Mix well, everything should be creamy. If it looks dry you may need more mayo.
Lastly, taste for salt and pepper. The salad is best after it has refrigerated for a few hours or overnight. Store in a sealed container and it'll last for a few days.
