Pre heat the oven to 200 degrees. If you are using a pastry case do not pre cook it. If you are using uncooked pastry - grease the dish and blind bake for 10 minutes. Add the apple and mince pie filling leaving a gap for the topping. I use two spoons of apple to one spoon of mince pie filling. For the topping combine the vegan margarine, ground almonds, sugar, flour and essence in a bowl making fine crumbs. Spread on the top of the dish pressing down. Bake for 10 minutes or until browned.
