These sweet and flaky apple turnovers are a perfect dessert for any occasion. The puff pastry is filled with a mixture of diced apples, cinnamon, sugar, and a touch of lemon juice. The turnovers are then baked until golden brown and crispy. Serve them warm with a scoop of vanilla ice cream for a delicious treat. To make them, simply roll out the puff pastry, cut it into squares, fill each square with the apple mixture, and fold it into a triangle. Brush with egg wash and bake until golden brown.
