Place cooled pie filling in a 1½pt pie dish - or similar. Place a pie funnel or upturned egg cup in centre of filling - this will hold up the pastry.
Unroll pastry and with a sharp knife cut strips of pastry from short edges of sheet and use to form a rim on the pie dish edge. Brush edge with beaten egg to help pastry to stick, then brush pastry rim with egg wash. Carefully lay remaining sheet over the pie dish, press down edges to form a good seal and trim off excess with a sharp knife. Glaze with beaten egg.
Bake for 25 minutes or until puffed and golden.
