Dab meat dry and cut into thin strips. Add starch, 1⁄2 TL salt, pepper, 1 TL sugar, oyster sauce, rice wine and 1 tablespoon oil to the meat. Knead everything well with your hands, then marinate for about 15 minutes.
Peel and finely chop the ginger. Remove any outer leaves from the Pak Choi. Wash the pak choi, shake dry, cut off the stalk and cut larger stems a little smaller.
Heat 1 tablespoon of oil in a frying pan. Fry the pak choi stems and ginger in it. Add remaining pak choi and soy sauce and steam briefly.
Heat 2 tablespoons of oil in a second pan. Fry the meat briefly over a high heat while turning. Stir in Sambal Oelek, fold in Pak Choi. Wash and chop the chives and sprinkle them over the meat. Serve with rice.
