How to reduce the fat level of a pie
Replace your usual pastry with phyllo pastry.
This pastry is very low in fat compared to other pastry types.
Use approximately 8 to 10 sheets of phyllo for the pie topping.
Instead of brushing each layer with oil, only brush with milk (dairy or soy). If wished, you can brush the top layer with olive oil to assist browning and crunchiness.
