Chinese pao fan, or soupy rice, was created a way to turn leftover cooked rice into a hot, satisfying meal in a bowl. This version, however, starts with uncooked rice. We simmer the grains with mushrooms in a mixture of broth and water and add bok choy (or mustard greens) at the end. To make this vegetarian, use the vegetable broth and hoisin instead of oyster sauce.
