STEP 1 Combine the steak slices with the marinade ingredients. Mix well. Allow to marinate for only a few minutes. STEP 2 For the stir-fry sauce, rinse the black beans well and finely chop. To the black beans, add the remaining stir-fry sauce ingredients and mix to combine. Set aside for later. STEP 3 Heat the vegetable oil in a wok or large frying pan over medium-high heat. Add the garlic, ginger and dried chillies. Stir-fry for 10 seconds. Then add the beef and spread the strips out in the pan quickly. Allow to sear for a minute or so before stir-frying. Repeat the spreading and stir-frying technique until the beef is almost cooked. Add the broccolini and stir-fry for a minute. Then add the bok choy and the stir-fry sauce and stir-fry until the bok choy is just wilted and the sauce is thick and glossy. Serve with steamed rice. *NOTES:You can replace Chinese Shaoxing wine with a little apple or pineapple juice if you’d rather not use it.Chinese salted black beans are available from Asian grocery stores or online.
