Tenderloin Sandwich

This ultimate steak sandwich is made with the most expensive cut of the steer, the tenderloin, the only cut tender enough that it doesn’t need to be sliced for a sandwich. One caveat: If you like well-done meat, don’t make this sandwich. Because it is so lean, tenderloin dries out as soon as it reaches the temperature needed to cook it beyond medium-rare. Each sandwich contains only a small amount of meat— you may want to offer 2 sandwiches per person.
