Blind bake the pie shell at 300 deg. for 10-15 minutes. Let cool while you sauté the apple in the butter for about 5 minutes. Combine with the cheese and scatter evenly over the bottom of the pastry shell. Sprinkle the cinnamon-sugar over the apple-cheese mixture.
In a medium bowl, lightly whisk together the eggs and whipping cream and pour over the apple-cheese mixture. Bake at 375 deg. for 50-55 minutes or until lightly browned and set. Oven temps vary so watch you quiche and bake accordingly.
