On lightly floured surface roll out your pie crust into a 10 inch circle and place into a 9 inch deep dish pie pan. Crimp the edges of the crust around the top of the pie pan.
Topping - add your topping ingredients to a food processor with the chopping blade installed. Pulse the food processor until the topping starts to clump and form small little beads.
Filling - Mix together the sugars, flour, cinnamon, and nutmeg in seperate bowl until well blended.
Add the sugar/spice mixture to the bowl with sliced apples and toss until the apples are well coated.
Transfer the apple mixture to your pastry lined pie pan.
Cover the pie with foil sprayed with non-stick oil spray and bake for 25 minutes. Remove foil and sprinkle your topping all around the top of the pie and bake for another 25 minutes or until topping is golden.
