One Pot Chicken Cider Pie
Preheat oven to 220°C/428°F.
Finely slice the leeks and cut the mushrooms into quarter. Melt a knob of butter in the pan. Add the leeks and cook for 3 minutes until wilted. Whack in the mushrooms with a pinch of salt and fry until soft. Sprinkle in the flour.
Melt the second knob of butter and use it to brush over 6 filo sheets. Crumple the pastry with your hands and place on top of the pie filling. Once the whole filling is covered transfer to the oven.
Cook for 20 minutes or until the pastry is golden brown.
Sprinkle over the remaining parsley and serve with mustard.
