I saw this on the BBC website and I'm trying to figure out if it's for real or if they are putting me on:
"For a toast sandwich, take a very thin slice of bread and toast it. Once cold place it between two slices of bread, also sliced very thinly. Butter optional. Salt and pepper to taste."
Apparently this recipe is taken from the Book of Household Management, published in 1861 by the food writer Isabella Beeton. The Royal Society of Chemistry is promoting it as "the UK's cheapest meal."
