This recipe is very flexible. Large chicken breasts cooking on low heat in flavorful juices will not dry out. On the flip side, if you need them done faster they will cook quickly and shred up nicely. So this chicken dinner can be cooked on the fastest setting for those of you who start your dinner later in the day or the slowest for those of you who like to get started early in the morning. Typical settings range from 4-8 hours.
