Ingredients: 250g puff pastry, 75g crispy fried bacon, 100g grated cheese, 1 beaten egg, and dried herbs (optional).
Preheat the oven to 200°C (390°F) and line a baking sheet with parchment paper.
Roll out the puff pastry and cut it into equal squares. Place the bacon and cheese in the center of each square and sprinkle with herbs (optional).
Fold the corners of the pastry over the filling and press the edges firmly together. Brush with the beaten egg.
Bake the pastries for about 15-20 minutes, or until golden brown and crispy. Let them cool briefly and serve warm. Enjoy!
