These sweet puff pastry turnovers are filled with tender apples, cinnamon, and sugar. The puff pastry is flaky and buttery, while the filling is sweet and spicy. To make them, simply sauté some apples with cinnamon and sugar, then cut the puff pastry into squares. Fill each square with the apple mixture, fold into a triangle, and bake until golden brown and crispy. Serve with a drizzle of caramel sauce for extra sweetness.
