Skin your chicken pieces, then rinse and add to your waiting crock pot.
In the meantime, add 1/4 cup of cold water and mix with your cornstarch to dissolve it before adding it to your pot to cook.
Add the remaining salt, brown sugar, white vinegar, pineapple chunks, soy sauce, and finely chopped onion next to that pot.
Cook the sauce ingredients until slightly thickened enough to a suitable consistency to put over rice and chicken.
Pour the cooked sauce over your waiting chicken, cover with your lid and cook on low in your crock pot for about six hours.
Serve the chicken on a bed of rice add a green vegetable or a fresh garden salad and you have a delicious, healthy dinner to present to your family.
