Wash the beef brisket, enoki mushrooms, and bean sprouts thoroughly and prepare them.
Trim off the base of the enoki mushrooms and separate them into bite-sized pieces.
Heat cooking oil in a pan and stir-fry the beef brisket first.
When the beef is halfway cooked, add the bean sprouts and enoki mushrooms and stir-fry together over high heat.
Season with salt and pepper.
Once all the ingredients are fully cooked, transfer to a plate and serve.
