Filet mignon refers to a high-quality cut of meat that originates from the small end of the tenderloin, a part of the muscle of an animal which rarely does any work, therefore, resulting in a tender piece of meat. It is widely known for its delectable taste and tenderness, making it one of the most sought-after and expensive cuts of steak. It is often cooked by grilling or pan-searing and is usually served in high-end restaurants.
