Add a little cooking oil to a pan and stir-fry the pork with 1 tablespoon of sugar and 2 tablespoons of soy sauce.
Once the pork is cooked, set it aside. In the same pan, stir-fry 1 tablespoon of soy sauce with 1/4 head of cabbage and half an onion, thinly sliced.
When the vegetables are cooked, combine them with the pork, then add half a stalk of green onion (diagonally sliced) and 2 Cheongyang green chilies (sliced), and stir-fry again.
