A "sirloin steak" can mean any of eleven different steaks. The sirloin steak is cut from the back of the animal. The top sirloin is the favored of the sirloin options. Top sirloin steak is flavorful and somewhat tender and can be cut into almost any size portion, made into kabobs, fajitas, and makes great steak sandwich recipes. Not quite as tender as cuts from the loin or rib. Approximately 1 lb.
