This week on Simply Ming, Iron Chef Masaharu Morimoto stops by the loft kitchen for a showdown. After a quick cucumber cutting challenge, these two amazing chefs cook up dueling versions of a traditional Japanese dish: Tonkatsu. While Iron Chef Morimoto doubles down and makes a traditional deep-fried pork cutlet tonkatsu and his house ramen, Ming counters that with a vegetarian version of portobello tonkatsu atop a fantastic house rice.
