Peel the walnuts.
Chop the walnuts in a blender.
Peel the apples and grate them using a coarse grater.
Add the sugar to the grated apples.
Add the chopped walnuts.
Add the vanilla essence.
Add the cinnamon.
Stir.
Grease the phyllo sheet with oil.
Place the apple mixture on the sheet. To make it easier, divide the apple mixture into 4 parts, as you will be using 4 phyllo sheets, and divide the apples evenly among the sheets.
Fold the sheet (push both ends of the sheet toward the middle).
Place the 4 sheets of apple pie in a baking tray lined with baking paper.
Pour the remaining oil over the sheets. Place the tray in an oven preheated to 180°C (350°F) for 40-45 minutes.
After removing the pie from the oven, sprinkle with powdered sugar while it is still hot, then cover with a towel and leave for 10-15 minutes. Then you can cut and serve.
The apple pie is ready. Enjoy!
