This is one of the "orphan recipes" I came across on here. However, my mom used to make these when I was a kid. She'd buy a loaf of french bread, slice horizontally along the side, add the meat mixture and freeze it. With 5 kids in the house during the summer, she'd make a few of these for us to make while she'd be at work. Since I was the youngest, my siblings would always "stick" me with the ends which to me is the best part!! I do remember the big loaves being wrapped in foil to bake. This does reheat well in microwave. We never had a microwave when I was a kid but there were never any leftovers either!
