you could make chicken parcels

cut the chicken into small pieces and lightly pan fry
wait for the chicken to cool, (put in fridge if need to)
take a few sheets of pastry out of freezer to defrost a little
place chicken, grated cheese and any other ingredients in centre of one sheet of pastry and wrap up like a parcel
other ingredients could include things like tinned pineapple pieces, sundried tomatoes, anything you like!
grease a baking tray with lots of butter
place parcels on tray all sealed up well, brush over with some egg
bake for about 30 mins 180 dg. yummo!
