Chicken Coriander Pie with Cider and Mustard

I make this pie in a round china flan dish and then everyone gets a good slice of the rich and crumbly pastry. The combination of flavours in the filling is delicious and the pie is very good eaten hot or cold for lunch or dinner, or you could make a larger version for a cold buffet. If you have it cold serve it at room temperature, not straight from the fridge. I do not think it needs potatoes with it, just a green salad You can make the pie well in advance, so with no vegetables to do it
