Pat the fish with kitchen paper, then dust both sides with cornflour. Heat a splash of oil in a large frying pan, then drizzle the skin on each fillet with a little more oil and add to the pan, skin-side down. Cook for 2-3 mins, turn and cook for a further min.

Meanwhile, heat the sesame oil in a large wok, add the ginger, chilli and spring onion and cook for 2 mins, stirring. Add the garlic and cook for a further min, then spoon over the fish. Add the bok choi and teriyake marinade immediately to the wok, cook over a high heat for 1 min until wilted. Serve with the fish, lime wedges and steamed rice.
