Waldorf Chicken Salad Sandwich

This used to be the salad for the ladies who lunch. When it was originally served at the Waldorf Astoria, it was just apples, celery, and mayonnaise atop a bed of lettuces. Walnuts were added later. I’ve added the chicken, although leftover cooked turkey works well, too. It’s a recipe that follows my theory–good salad, great sandwich filling. It can be served on white bread, white toast, or walnut bread, if you can find an acceptable commercial loaf.
