Vegetarian club sandwich with hummus and roasted sweet potato

The first reference to the word sandwich as an English cold food is documented in the journal of the English historian Edward Gibbon in 1762. The sandwich has a history that dates back to the 18th century, starting with the English aristocrat John Montagu, 4th Earl of the Sandwich, although he was not its inventor. It is said that he liked to eat like this because that way he could play cards while eating, without getting his fingers dirty.
