16oz Chairman Reserve® Boneless Ribeye. Sure you can buy any old steak at the grocery store for a little less money. But check the marbling. The small white flecks of intramuscular fat. That’s marbling. Why does it matter? Marbling affects tenderness and overall eating experience. Our 16oz Boneless Ribeyes are beautifully marbled so you know they will hold flavor and tenderness just the way you like.
