The easiest apple pies in the world are here.
All you have to do is slice your apple.
Remove the seeds. Roll out the puff pastry sheet and cut it into strips.
Take a strip of puff pastry and start passing it through the hole in the center of the apple slice.
Do the same with all the apple slices.
Preheat the oven to 180C. Bake for 15-20 minutes.
