I heard the salami was a nod to thr Italian population in Ybor City. There is still a heavily Sicilian community in the area.
hmm is it pork or beef salami used? - tho the roast pork and ham in the sandwich already indicate that the eater is not a person concerned about pork consumption.
Im sure there may be a few shops that use beef, the default is definitely pork.

“A Tampa treasure!” the menu proclaims. The Cuban, it continues, started as a snack for cigar workers in the 1890s. “The sandwiches underwent changes as immigrants from different countries came to Ybor City… The Spanish brought the fine ham, the Sicilians the Genoa salami, the Cubans the mojo-marinated roast pork, the Germans and Jews the Swiss cheese, pickle and mustard.”
There was a wonderful spot in suburban DC that served a sandwich, on French bread, that consisted of ham AND cheese (melted onto the ham) AND lobster salad : more than a warning - a triple traif! (It was my favorite).
