Line a casserole dish with foil. Combine ingredients and spread in casserole. Spray lightly with olive oil spray. Cover with foil.
Bake mixture in 350°F oven for 30 minutes, uncovering during the final 10 minutes.
Place pie crust on a silicone or parchment lined baking sheet.
Make 4 mounds of mixture on the bottom half of pie crust, one for each pie quarter. Brush edges and inner sides of circle with water. Cover with second pie crust. Using a sharp knife, divide along an X in the center of the circle (see diagram).
Brush tops of pasties with 1 egg white beaten with 1 tablespoon of water for an extra shiny crust. Cut a vent hole (or two or three) through the top crust to allow steam to escape.
Bake at 375°F until tops are golden brown (about 30 minutes). Reduce temperature if edges are browning too quickly in your oven.
