To make the crust:
In a large bowl, combine the flour, sugar and salt.
Add the butter and eggs and mix with your hands until the dough comes together.
Wrap in plastic and refrigerate for at least 30 minutes.
Let the dough sit at room temperature for 10-15 minutes before rolling out.
To make the filling:
Make sure the greens are completely dry.
If necessary, dry them with paper towels.
In a large bowl, combine the sugar, eggs, cheese, raisins, pine nuts, marc, olive oil, pastis, salt and pepper. Stir to combine.
Add the greens and stir again.
Preheat oven to 375 degrees F.
Halve the dough and roll out to ¼ thickness.
Place one half in a 9-inch pie dish and press into the corners with your fingers.
Distribute the filling evenly and cover with apple slices.
Cover with the other half and press the edges to close the pie.
Pierce the top with a fork in several places.
Bake for an hour, until the top is golden brown.
Take the pie out of the oven and dust with powdered sugar.
Serve warm or at room temperature.
