Premium USDA Choice beef flank steak from Kirkland Signature, vacuum-sealed in Cryovac packaging for extended freshness. This lean cut comes from the abdominal muscles of the cow and features minimal marbling with strong grain structure. Ideal for high-heat cooking methods including grilling, stir-frying, and marinating for fajitas or carne asada. The muscle fibers run in long, visible lines across the length of the steak, requiring slicing against the grain for optimal tenderness.

Contains no added ingredients, preservatives, or additives and is naturally gluten-free.
