Around for a Long Time
Compared to how long sandwich-like dishes have been around, their current name is a novelty, named after John Montagu, the fourth Earl of Sandwich. Known to be a hardened gambler who liked to play uninterrupted for hours at a time, he asked his valet to bring him a slice of salted beef between two toasted slices of bread. Others would follow his example and order “the same as Sandwich.”
