Hot Beef and Chili Bean Plank Sandwich
I'd never heard of a "plank sandwich" before, but apparently it really was a thing because this one was featured in Bell's Best 2 published in 1982, the second in the series of Mississippi Telephone Pioneers community cookbooks. Even still, I thought it was just one of those recipe names that a family came up with.
So, I turned to AI to find out if there was such a thing as a plank sandwich and was told:
A plank sandwich typically refers to a sandwich made using thick slices or "planks" of bread or other ingredients, often layered with various fillings. It can also refer to specific recipes, like a Monte Cristo breakfast plank, which involves dipping bread planks in an egg mixture and cooking them with fillings.
