This is not a traditional Waldorf salad, but using it as my inspiration, I made a delightful post-Thanksgiving turkey salad.
Chop up 1 apple (Gala) and 1 celery stalk. Chop 4 oz of turkey white meat. Add an ounce or so of dried cranberries and about 6 almonds, sliced in half and toasted. Mix together and dress with 1 TBSP of mayonnaise and the juice from half a fresh lemon. Add salt and pepper to taste.
I think walnuts or pecans would have been meatier and better in the salad than the almonds, but it was still delicious. The dried cranberries add a tart sweetness that is even tastier than grapes.
