This takes no time at all.
- shop-bought puff pastry ( preferably already rolled)
- 5-6 apples cut into thin slices
- 2 handfuls of caster sugar
- one egg beaten
Preheat the oven at 200 degrees. Line an oven tray with baking parchment. Put the puff pastry on top. Arrange the apple slices on top of the puff pastry. Sprinkle it with the sugar, paint the puff pastry edges with the egg wash and bake for 20-25 minutes.
You can also put apple sauce under the apple slices. Or you can toss the apples with the juice and grated zest of a lemon.
