Unroll one store-bought pie crust and gently press it into a 9-inch pie plate. Use your fingers to press it firmly against the pie plate, especially along the edges of the pie crust, so it holds the filling well.
Make the Apple Filling - In a large bowl, mix together the 2 cans of apple pie filling, cinnamon, and nutmeg. Stir until the spices are evenly distributed through the apple filling.
Pour the apple mixture into the prepared bottom crust and spread it out evenly.
Add the top crust. You can pace it whole and cut a few slits on top of the pie, or you can do as I did and make a lattice crust.
Brush the top of the pie with a light coating of egg white using a pastry brush. This will help it bake up golden brown and shiny.
Bake the pie for 45 minutes, or until the crust is golden brown and the filling is bubbling. Remove the pie from the oven and let it cool on a wire rack for at least 30 minutes or until it reaches room temperature before slicing.
