Preheat the oven to 180°C.
Start by preparing your pie crust.In a bowl, pour the flour, oil, water and a pinch of salt.Knead quickly until you have a ball of dough. Be careful to knead as little as possible so that the dough is not too hard and keeps its crispness, a pie dough does not knead.If the dough is too sticky add a little flour, if it is too dry add a little oil and/or water. Lightly flour your work surface and roll out the dough and place it in a pie pan or flat on a baking sheet lined with parchment paper. Prick the base with a fork.
Peel and slice the apples. Lay them flat on the dough.
Place the coarsely chopped nuts on top of your apples.
Bake for 35 to 40 minutes on low in your oven (the top of the pie should be golden brown).
Serve hot or cold with salted butter caramel, or sprinkle with vanilla sugar.
