Preheat oven to 375F. Put the ready-made pie crust, I used Pillsbury, on a piece of waxed paper. Cut with cookie cutters. Gather the leftovers, press together until you make a small ball and use a roller to roll the dough until it is the same thickness as the original pie crust. Continue cutting with the cookie cutters until you have used all the dough.

Mix one egg with two tablespoons of water or milk to make egg wash. Brush egg wash on the cut dough shapes. Sprinkle with Parmesan cheese.

Line a cookie sheet with parchment paper. Pace the dough Halloween shapes on the cookie sheet and bake for 8 minutes or until golden brown.
