Instructions

  1. Mix together the ketchup, diet cola, vinegar, hot sauce and onions in a large skillet. Add the chicken breasts and bring the sauce to a boil over medium high heat.
  2. Reduce to a simmer and cook for 50 minutes, until the chicken is tender enough to split with a fork. The sauce will be reduced by half and quite rich and thick.
  3. Serve each breast with a quarter of the sauce.
