Crockpot Sweet and Sour Chicken

This is very similar to Cantonese Chicken, with a few simple changes for it to work in the Crockpot.

1.  Make sweet and sour sauce in the bottom of the Crockpot.  You may want to add extra cornstarch to help it thicken better during the juicy slow-cooking process.
2.  Add four frozen chicken breasts, one cubed onion, and cook on low for 8 hours.
3.  Turn off the Crockpot, add cubed tri-color bell peppers and cubed pineapple to the top, recover, and allow vegetables to become tender.
4.  Break up chicken into smaller pieces, stir everything together, and serve over rice.
