From America's Best Lost Recipes, cookbook. If you like bologna, then this is the pie for you. We could find no precedent for this particular recipe and had to rely on Barbara to give us a few clues as to its origin: "As a young homemaker on a tight budget, I became very inventive when it came to stretching a pound of meat to feed my family. This recipe was a spin-off of the Michigan Pasty, a ground beef, potato, and onion combination wrapped in pie crust. My first version did not include a crust. I cooked the ingredients in an electric fry pan and served it from the pan. Some time later, I decided to change its presentation and piled the browned and partially cooked ingredients into a pie plate, added a top crust, and baked it. My creation became Mile High Bologna Pie. When my daughter-in-law asked me how to make this dish, I knew my son, who is fussy about his food, really liked it." Barnara Estabrook-Rhinelander,Wisconsin
