Some five hundred years ago, the Taíno tribe created the first Cuban sandwich. The primordial version featured casabe, a kind of crispy flatbread made from the yucca root. The filling was either fish or bird meat, layered between two slices of casabe. When the Spaniards arrived on the island of Cuba, they introduced pork to the natives, and swapped the casaba for a bread-like alternative, hence birthing a new riff of the Cuban sandwich. Circa the mid-1800s, the Cuban tobacco industry began to flourish in Florida, and naturally the immigrants brought this beloved dish to their new home — the sandwich, being affordable, was a common choice for lunch. So it was that the Cuban sandwich became popular.
