In puerto rico, jibaro is a reference to the island's rural, agrarian population. However, in chicago, a jibarito is a unique and original sandwich created by puerto rican immigrants at the borinquen restaurant in humboldt park. Today it is served throughout the city. The distinguishing feature of this sandwich is the replacement of bread with smashed, fried plantains. It's brilliantly delicious and you can add any of your favorite sandwich fixings. This particular jibarito recipe features roast beef topped with swiss cheese, lettuce, tomato, and a spiced mayonnaise. You can make these full-sized and enjoy them as a meal or cut the plantains down and build them into small party sandwiches.
