Pre-heat your oven to 350°F.
Take one ball of dough, and roll it out on a lightly floured surface to about 1/8 inch thick.
Cut circles out of the dough using a 3 inch round cookie cutter. Re-roll any scraps and cut out additional circles until the dough is all used up. Repeat with the other balls of dough.
Place the dough circles on a parchment lined baking tray. Brush the edges lightly with the egg wash.
Drop a heaping teaspoon full of pie filing onto the centre of each dough circle.
Place a second dough circle on top of the filling. Use a fork to press down and seal the edges of the pie crust.
Brush the tops of each pie with the egg wash, and generously sprinkle with some granulated sugar.
Cut a small slit into the top of each pie crust to allow the steam to vent.
Bake pies at 350°F for 25-30 minutes, until the crust is golden brown. Allow pies to cool slightly before serving.
