San Jeok (산적) is a Korean holiday food. We usually make this food with family and relatives one day before a holiday, and serve it the next day. The color and taste combination of this food is very good. Depending on your tastes, you can skip the crab or add different kinds of vegetables, such as mushrooms, carrots, or zucchini. If you are a vegetarian, I recommend using mushrooms instead of beef (oyster mushrooms will be the best). Use the same sauce to marinate mushrooms, cook them until they get enough bulgogi sauce flavor, and then skewer them instead of the beef.
