Slice the shiitake mushrooms, cut the carrot into 1cm slices, and chop the chives into bite-sized pieces.

Heat sesame oil in a pot over medium heat and sauté the beef until its color changes.

Add shiitake mushrooms and carrot, stir until coated with oil, then add the seasoning ingredients and bring to a boil. Skim off any foam and simmer covered on low heat for 5 minutes.

Add chives and mix briefly.
