Seiyu's "On the Gohan Roulou Rice" Series - All you have to do is heat it up and serve it over rice! Easy Taiwanese Rice
I actually purchased and tried On the Gohan Roulou Rice 120g, sold by Seiyu. Pork belly, bamboo shoots, kikurage mushrooms, and shiitake mushrooms are seasoned with sweet and spicy octagonal and oyster sauce.
