Cut off the root end of the enoki mushrooms and wash them thoroughly.
Tear the enoki mushrooms into bite-sized pieces and set aside.
In a bowl, mix together gochujang, red pepper powder, soy sauce, sugar, minced garlic, buldak sauce, and sesame oil to make the seasoning sauce.
Evenly coat the enoki mushrooms with the seasoning sauce.
Heat cooking oil in a pan and stir-fry the enoki mushrooms over medium heat.
Once the seasoning is well absorbed and the enoki mushrooms have softened, turn off the heat.
Transfer to a plate and garnish with sesame seeds and finely chopped green onion to finish.
