Add tofu, mung bean sprouts, enoki mushrooms, and mini napa cabbage to a pot, pour in just enough water to barely cover the bottom, then season with Yondu and Korean chili powder.
Wash the vegetables thoroughly and cut them into bite-sized pieces.
Pour water into a steamer and bring to a boil.
Arrange the vegetables evenly on the steamer rack.
Cover with a lid and steam over medium heat for 10-15 minutes.
Serve with salt or sauce.
