Heat a chapa or one or two large cast-iron skillets over high heat. Brush the steaks with the olive oil and sprinkle with coarse salt. When the surface is very hot, add the steaks and sear them, without moving them, for at least 1 1/2 minutes or until well browned -- lift up an edge of one steak with tongs to check. Turn the steaks and cook for another minute, or until done to taste. Transfer to a platter and let rest for 1 minute.
Serve with the chimichurri.
Serves 4.
