I also go the celery seed route. I generally smoke a family pack of savory rubbed chicken breasts, and use some for other dishes, but reserve some for chicken salad. I add walnuts, apples, celery, onions, sweet peppers, and usually cranberries, in the theme of Waldorf salad. To make it less oily, I use half mayo, and half sour cream. I am actually making some tonight for lunch tomorrow. It is better when the mix sits overnight.
