In these skirt steak sandwiches, skirt steak, which cooks to medium-rare in just about 5 minutes, is layered with arugula between slices of focaccia smeared with herbed mayonnaise. The key, as with all meats, is to let the steak rest for at least 10 minutes before slicing, and with skirt steak, to slice it thinly against the grain. // alexandracooks.com
