Set up your crock pot.
Dice the apple and onion, transfer to the crock pot.
Season the chicken breast and thigh using the salt and transfer to the crock pot.
Place 1/3 cup apple cider vinegar and 2/3 cup water into the crock pot.
Set your crock pot to low for 4-6 hours (ours our usually ready about 5 hours. If they sit in the crock pot too long they will get mushy, and you don’t want that!)
About 15 minutes before I serve the chicken, I like to shred it so it nicely soaks up the juices. If you shred too early, it will get mushy!
For the sandwich, I serve on a pretzel bun with some mashed avocado and viola – a perfect meal!
