A long, cylindrical, boneless cut of meat from the loin section of beef, pork, veal, and lamb. The Tenderloin extends from the rib cage to the pelvis. It is very tender and is one of the most desirable cuts of meat, although it is very expensive and lacks the flavor of other, less tender cuts. It is best when roasted or grilled, but care should be taken not to overcook it. The Tenderloin may be cooked whole or it may be cut into thick, single serving slices, which can be broiled or grilled. When sliced into smaller, round individual servings, the Tenderloin may be referred to as a filet mignon or a tournedo.
