Medianoche
Medianoche is a type of sandwich which originated in Cuba. It is served in many Cuban communities in the United States. It is so named because of the sandwich's popularity as a staple served in Havana's night clubs right around or after midnight.
A medianoche consists of roast pork, ham, mustard, Swiss cheese, and sweet pickles. It is a close cousin to the Cuban sandwich, the chief difference being that a medianoche is made on soft, sweet egg dough bread similar to Challah rather than on crustier Cuban bread. Like the Cuban sandwich, the medianoche is typically warmed in a press before eating.
In Jeff Lindsay's Dexter novels, Dexter names the medianoche as his favorite food.
