Roll out the pie crust dough from the Homemade Country Pie Crust recipe. Spray a 10" pie plate with Pam cooking spray. Roll out one crust and place in pie plate. Spray the dough (inside and edges) with Pam cooking spray.
Peel, core, and pare apples into thin slices. Put in a 3 qt. microwavable bowl. Add sugar, flour, cinnamon and margarine (do not mix yet--just add ingredients). Cover with Saran wrap and put in microwave for 5 minutes on high. Remove from microwave and stir completely. Put Saran wrap back on, put back in microwave for 5 minutes on high. Stir. Pour the apple filling into the pie crust.
Make a second crust slightly bigger than the first crust. Place on top of pie so that second crust hangs 1/2" over the edge. Pinch two crusts together and tuck second crust overlap under the first crust. Make edges fancy using a fork your fingers.
Place pie on top of a cookie sheet to catch any filling that cooks out. Sprinkle some white sugar and cinnamon over the top of the pie. Take a paring knife and poke holes all the way through the pie and all around the top of the pie. Right in the center of the pie, lift crust slightly and cut a small hole for air. Cover the edge of the pie crust with foil (or use a pie shield) so edge doesn't get too done. Place in oven and bake at 375 degrees for 45 minutes. After 45 minutes, remove foil/pie shield and bake for 15 more minutes or until crust is nice and brown.
