Pour 2 tablespoonsful of the marinade into a frying pan on medium heat. When hot, add the chicken breasts.
Cook gently on each side over medium-to-low heat, pouring a little of the marinade over from time to time.
It is important not to overcook them. A thermometer is the best way to check this. Stop the cooking when the centre of the chicken breast reaches 80°C (176°F).
