Now that we're moving past the holiday season, it's natural to start thinking about lighter meals. "Lighter" doesn't have to mean "bland" as evidenced by this flavorful Japanese inspired dish featuring Snake River Farms Flat Iron steak lightly marinated in miso.

Thanks to Harry Soo, the award winning, barbecue master behind the Slap Yo Daddy competitive BBQ team, for sharing his recipe. Harry used our Gold Grade flat iron teak for his recipe, which is a fantastic choice. This marinade would also be great with our Black Grade American Kobe beef or Double R Ranch Northwest beef flat iron steaks.
