Or why don't you cook them on top of a bed of tomato, onion and red peppers. Don't add any liquid, just sprinkle some salt onto the tomato etc, pop the chicken breast on top, put a lid on the pan. Bring to top heat slowly and them turn it down to low and steam the chicken through the veg. It is a delicious way to cook chicken breast which tends to be dry if cooked on it's own. It makes it's own liquid which is a really nice sauce for your potato or whatever you are serving it with.
