Quick Chicken Salad Sandwich

Every time I make chicken salad it's never the same, just a little of this and a little of that, whatever I have on hand.
You could combine any of the following:

chicken diced or shredded, canned or leftovers
celery chopped
onion minced
chives minced
parsley, finely minced
apple chopped
grapes halved
cheese shredded
dried craisens
mayo
celery seeds
salt & pepper

To make the sandwich spread a nice thin layer of dijon mustard on your toasted bread, then a nice crunchy piece of lettuce, few thin slices of apple, and a good spoonful of chicken salad.
