Shred leftover pesto chicken. Depending on how much chicken there is and your preference will depend on how much of everything else you use.
I had 1/2 a chicken left, so I used about 2T pesto, 1/2 an apple diced, a good dozen grapes cut in half, about 1/4 cup of pecans and 1 stalk of chopped celery. I mixed it with about 1/3 cup of mayonaise.
This can be served on bread, crackers, a bed of lettuce, or eaten plain. Man oh man is it good!
