Cut the tofu into bite-sized pieces.
Trim the root end of the enoki mushrooms and rinse under running water.
Heat cooking oil in a pan and grill the tofu on both sides until golden brown.
Place the enoki mushrooms on top of the tofu.
Mix soy sauce, water, sugar, minced garlic, and sesame oil to make the sauce.
Pour the sauce over the tofu and enoki mushrooms.
Cover with a lid and simmer on medium-low heat until the sauce reduces.
Finish by sprinkling chopped green onions on top.
