First, make a pastry crust. This is whole wheat flour, pecans and coconut oil - just enough ice water to make it stick together. It's a thick, hearty and rustic crust.
Then press into a spring form pan, fill with sliced apples and sprinkle with cinnamon sugar. Bake at 350F until the apples are tender.
When done (~one hour), remove from oven and brush with a pastry glaze (prepared from apricot jam).
Serve with (vegan) ice cream or froyo.
