As anyone who has spent time in Tampa knows, the Cubano -- originally called a mixto -- was created in that city. (Around the turn of the last century they were sold as portable lunchtime treats for cigar factory workers in Ybor City, Tampa's Cuban quarter.)
The Tampa-style mixto, which includes salami, is the starting point for C. Señor's Key West Mix, which adds lettuce and sliced tomato, traditional accouterments in Key West, where Alvarez grew up.
A delicious mix? Sí, señor.
