The cafeteria at my HS used to serve these. I lived very close to school, so I always went home for lunch. I have no idea how big they were or exactly what was inside them, but they always sounded so good!
I am using store bough rolls, they are better then anything I can make and no flour on the floor! I am letting the mix cool, it seems like most of the recipes I have seen, including yorkdude's CB ones a few years back, only use one biscuit. So will try not to over fill them. Gonna put cheese in half. Not traditional, but I like German Calzone!
