In a medium bowl, combine the cooked spinach, ricotta cheese, Parmesan cheese, garlic powder, salt, and pepper. Mix well.
Assemble the Pastries:
Roll out the puff pastry sheets on a lightly floured surface.
Cut each sheet into 4 squares (you should have 8 squares total).
Place a spoonful of the spinach and cheese mixture in the center of each square.
Fold the pastry over to form a rectangle or triangle and press the edges with a fork to seal.
Transfer the pastries to the prepared baking sheet.
Apply Egg Wash:
Brush the tops of the pastries with the beaten egg for a golden finish.
Bake:
Bake in the preheated oven for 15-20 minutes, or until the pastries are puffed and golden brown.
Serve:
Let the pastries cool slightly before serving.
