Spray Crock Pot with cooking spray.
Place 4-6 boneless chicken breasts in Crock Pot.
Cover with a bottle of Hawaiian BBQ sauce. (Target’s Archer Farms makes a good one.)
Empty in a 20 oz drained can of pineapple chunks.
Cook on high for 2 1/2 hours or low for 5 hours.
Shred chicken with a fork & mix with the sauce. Serve over rice or pasta.
