Mix together all of the ingredients. Stir with a fork until thoroughly mixed. Do not over-work the dough.
Shape this mixture into a ball and place it between two pieces of wax paper that have been dusted with flour. Roll the pastry into a circle large enough to fit in a 9-inch pie pan.
Spray pan with a non-fat cooking spray and Arrange crust in pan. Cut off the edges that hang over.
Prick the bottom with a fork and brush over with a little bit of beaten egg white. Bake 10 minutes or until golden brown. Cool before adding filling.
It's probably a good idea to prebake it before using it in almost any recipe.
Note: If you are making a pie where the filling needs to be cooked with the shell, simply bake at 350°F for 45 minutes or however long the recipe calls for. Work foil over edges while baking so the crust won't get overbrown. Remove foil for the last five minutes.
