Griddled lean steak and melted queso mantecoso in a marraqueta roll.

About Barros Luco
Pilar Hernandez describes Barros Luco as a traditional Chilean quick lunch, recalling the sandwiches made in her college cafeteria. This marraqueta rendition uses the lean steak and queso mantecoso she identifies with Chilean practice.
The meat is sliced thinly, seasoned with salt and pepper, and seared on a buttered griddle. The split bread warms alongside it while the cheese melts over the steak.
Bread, steak and melted cheese are stacked together with the meat’s juices. The sandwich is served immediately, keeping the preparation focused on its simple beef-and-cheese combination.
