Made this recipie from the kids section of 'how to eat'.
(put mash on top instead on pastry)
OMG it is SOOOOO yummy. I highly recommend it and its a great way to use up chicken left over froma roast!
Also REALLY quick, so easy and also cheep too, plus so long as you have left over chicken you are likely to have all the ingrdiants in your cupboard regardless
