I have a friend in Duxbury, MA, who used to describe herself as the "hamburger queen." This recipe was concocted for her to show her that ground meat can not only be truly tasty, but also elegant, exotic and fit for company... This recipe is Bohemian in origin. You may substitute commercial puff pastry, if desired, although it will change the texture and make the results much heavier. Fussing with the phyllo is worth the time and effort.
