Preheat the oven to 400°F (200°C).
Roll out the puff pastry on a lightly floured surface.
Cut the pastry into squares or circles, about 4 inches wide.
In a bowl, combine the shredded cheese, crumbled bacon, garlic powder, salt, and pepper.
Place a tablespoon of filling onto each pastry piece.
Fold the pastry over to form a triangle and seal the edges.
Brush the tops with beaten egg.
Place the turnovers on a baking sheet lined with parchment paper.
Bake for 20-25 minutes or until golden brown.
Let cool slightly before serving.
