Chop up the ginger and sauté in the sesame oil in a skillet.
Add and sauté the enoki mushrooms, shiitake mushrooms, and Chinese cabbage.
Add mentsuyu, mirin and water (not listed) in the skillet to taste the sauce. It should taste a little strong if the liquid just covers the vegetables. Add the katakuriko slurry (katakuriko dissolved in water) and bring it to a boil.
Cut the tofu into your preferred sizes, pour over the sauce and enjoy.
Story Behind this Recipe
I wanted to eat something healthy and that'll also warms me up.
You don't need to be picky about the ingredients or seasoning. Anything you like is fine. If the taste is too strong, simply dilute with water and increase the amount of the sauce (note that the liquid from tofu dilutes the sauce, so it is better to make the taste slightly concentrated at first).
Microwave right before serving, so the tofu softens nicely.
