Preheat oven to 425 degrees. Peel, core and slice apples.
In medium microwave-safe bowl, combine apple slices, sugar, flour, cinnamon, and nutmeg. Stir until mixed well. Heat in microwave for 7-10 minutes until apples have begun to soften. Set aside while you prepare the pie pastry.
In medium sized bowl, mix together flour and salt. Add shortening and cut in with a pastry fork until crumbly. Add 1/8 cup water and mix, then add the rest of the water to finish mixing the dough. Dough should hold together in a ball.
Roll dough out on floured surface the size of your pie plate. Crimp edges of pie. Add apple mixture on top of the unbaked crust.
In a small bowl, combine brown sugar, flour, oats, and cinnamon. With a pastry fork or your fingers, cut in butter until mixture is crumbly. Sprinkle over apple filling.
Place on second lowest rack in your oven and bake for 15 minutes. Lower oven temperature to 375 degrees and bake another 35-40 minutes until top is golden brown, using aluminum foil if necessary to prevent edges from getting too dark. Allow to cool on a wire rack.
To serve, drizzle caramel over the top of the pie as desired. Serves 8.
