Prepare the filling: Drain the canned peaches and chop them into small, bite-sized pieces. In a bowl, mix the peaches with sugar. Set aside and let the mixture sit for a few minutes to allow the juices to release.
Preheat the oven: Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper for easy cleanup.
Assemble the turnovers: Roll out the puff pastry on a lightly floured surface. Cut the pastry into squares or rectangles, depending on your preferred turnover size. Spoon a small amount of the peach mixture into the center of each square, leaving a border around the edges.
Seal and bake: Fold the pastry over the filling to form a triangle or rectangle shape, pressing the edges together to seal. You can use a fork to crimp the edges for a decorative look. Place the turnovers on the prepared baking sheet and bake for 20-25 minutes or until golden and puffed.
Serve: Once baked, remove the turnovers from the oven and let them cool for a few minutes before serving. Pair them with a refreshing cup of hibiscus mint tea for the perfect combination.
