Nestled in a brick-red shopping center in Doral is Mi Lindo Ecuador. Behold the bolón. In the morning, find it in a breakfast that includes salty white cheese and crisp shards of chicharrón alongside a fried egg and chopped flat steak. At night, order it as an appetizer or side dish with an empanada de verde con queso. For this four-biter, a single unripened plantain is pounded as thin as dough and wrapped around a sturdy rectangle of salty white cheese. Settle in for a bowl of caldo de salchicha, in which a fragrant broth simmers with all the deliciousness of fat blood-sausage links. It's all freshened up with plantain slices and green onion.
