Zest told me that cooked chicken can be used in a stir fry but it needs to be properly reheated. I simmered it in some chicken stock (made from the chicken carcass and some vegetables) while making the stir fry. I used sesame oil for a change and finished it off with sweet chilli sauce.
I served it with noodles for the carbs. element but it would be good on its own too.
