Roll each crust into a 14” square and cut into 4 equal squares. Place 1/3 cup filling on each square, brush edges with water and fold dough over filling to enclose. Crimp edges with a fork and brush with egg wash. Cut three slits in top to vent.
Transfer to 400 degree oven and bake until golden brown, 10-12 minutes if using pie crust and 20-25 if using puff pastry.
These are perfect for making ahead and popping in the freezer. Just wait to do the egg wash until you are ready to bake them. To cook from frozen, adjust baking time to 25 minutes.
