Crockpot method--do NOT brush chicken with the olive oil. Place chicken in the bottom of a large (6-7 quart) crock pot or casserole crock. Ideally, they should be in a single layer so I recommend the casserole crock. Cook on high for about 3 hours then drain off any liquid that accumulated. Pour sauce over chicken and cook for an additional 1-2 hours, or until chicken is done.
