It's a sandwich but what is in it depends on where you get it. We got
frozen ones when I was a kid. They came on a submarine roll and I'm pretty
sure that the fillings were cheap bologna and American cheese. You baked
them in the oven to heat through. I didn't particularly like them but they
were cheap and easy to fix. My friend and I often chose those for dinner
when we had sleepovers and had to get our own meals. We would also get
frozen turnovers which weren't really cheap. But the Po Boys were cheap
enough that it allowed us enough money left over to get the turnovers.
