Sándwiches de miga, or crumb sandwiches (which refers to the bread without its crust) resemble English tea sandwiches or Italian tramezzini, and are likely to be descended from them. They are sold as single-layered sandwiches with 2 very thin slices of bread (simples), or they can also be stacked with three slices (triples). At their most basic, they are filled with a slice of ham, a slice of cheese, and slathered with some mayonnaise. But what makes these crumb sandwiches so appealing is their extensive variety of fillings. Eggs, olives, tomatoes, hearts of palm, avocado, and peppers are paired in different combinations with fresh and cured meats or poultry to create a spectacular array of colors and flavors.
