I use however much chicken we'll eat in one sitting, which is 2 chicken breasts. Just make sure the chicken is covered by the sauce.
2 skinless boneless chicken breasts
1/2 bottle of favorite BBQ sauce (or enough to cover chicken)
1/2 c water
Combine all ingredients into crockpot.
Put on low for 4 hours.
strain out chicken and shred.
If sauce in Crock pot is watery, add more BBQ sauce.
Put chicken back into sauce.
Serve with rice, potatoes, mashed potatoes or anything! Very yummy!
