To Prep
In a mixing bowl, add all marinade ingredients and mix well until sugar is dissolved.
Add chicken slices to the bowl and coat evenly with marinade. Set aside to marinate for at least 30 mins or overnight in the refrigerator.
To Cook
Preheat a grill pan (or frying pan) over medium high heat. Then, using a pair of thongs or chopsticks, add chicken slices to the pan while reserving the marinade. Cook until slightly caramelised, about 2-3 mins on each side. Reduce heat slightly to avoid burning, and add the reserved marinade spoon by spoon as the pan gets dry.
Serve dak bulgogi on its own, or with leafy greens (iceberg lettuce, cos lettuce or mustard green) as a wrap, or with steamed rice.
