Fresh fryer boneless skinless chicken breast with rib meat is sold by the pound at Costco's meat department. These are fresh (never frozen) chicken breasts trimmed of skin and bones, with the rib meat portion still attached for a fuller, meatier cut. The rib meat section is the thin flap of muscle that runs along the underside of the breast near the ribcage, commonly left on to add weight and tenderness to the portion.

As a lean, high-protein meat, boneless skinless chicken breast is one of the most versatile proteins available. It can be grilled, baked, sauteed, poached, or stir-fried. The fresh fryer designation indicates the birds are young and tender, ideal for quick, high-heat cooking methods. Always cook chicken to an internal temperature of 165°F as measured with a meat thermometer. Store refrigerated and use within 1–2 days of purchase, or freeze for longer storage.
