Cut large circles out of the pie crusts and place them into a cupcake pan. Fill each spot with apple pie filling. Use the remaining pie crust to cut smaller circles to top the pies. You could also leave off the top for a tart-type dessert. If you do a solid circle, use a fork to make venting holes. Push the top together with the bottom. Brush a little bit of egg white 'wash' onto the tops of each pie and sprinkle with sugar. Bake for 20 minutes at 425 degrees.
