There was a drive-in restaurant in my hometown of Moberly MO in the 50's and 60's. It was called Pig n Bun. They were best known for Juicyburgers which were created by the owner, Albert Patrick. You'll find them similar to Sloppy Joes. This is my mother's copycat recipe that she created. From the kitchen of Wanda Cupp Thornburg, Moberly MO.
