Koreans love to eat bulgogi by placing a small amount of steamed rice in a lettuce leaf, a slice of bulgogi and small amount of kimchi (pickled fermented vegetable available in Asian stores). Roll up and eat.

Variation:
Instead of green capsicum, use green beans or English spinach lightly blanched and stir-fried. Several kinds of mushrooms can also be used to make ‘Mushroom Japchae’.
