Chuck,
I haven't done chicken salad yet, but I have done smoked turkey salad with leftover turkey that I smoked. I suppose it would be similiar. I just chopped up the remaining meat, put it in a bowl with just a little sprinkle of your favorite rub, then mix it with celery and mayo. It came out great. I also make turkey soup. That comes out awesome. Make your own stock with the bones, then strain and mix in carrots, celery, onion and wild rice. It comes out awesome.
