Preheat oven to 350 degrees. In a skillet melt butter and toss in apple slices, sugar and cinnamon. Cook over medium heat until apples begin to caramelize or begin to get glazed with sugar and butter. Roll out puff pastry in a freeform shape and roll in outer edge about a half inch to form crust. Spread warm apples on top of pastry. Brush crust with egg wash and sprinkle with sugar. Bake for 20-30 minutes or until golden.
