Preheat the oven to 350 degrees F (180 degrees C) and thaw out Puff Pastry (2) according to the instructions on the box.
Mix Egg (1) and Water (1 tablespoon) to create egg wash.
Cut shapes from puff pastry using a cookie cutter.
Lay shapes onto a sheet of parchment paper on your baking pan and brush with egg wash.
Sprinkle a little Shredded Mexican Cheese Blend (1/4 cup) onto each shape.
Bake for 10 minutes or until cheese has melted and pastry puffed.
