To make the green chilli nam jim, use a mortar and pestle or small food processor to pound or process all the ingredients until smooth.

Step 2

Heat the oil in a large non-stick frypan over medium heat. Season the fish with sea salt and freshly ground black pepper and cook for 2-3 minutes on each side until cooked through.

Step 3

Meanwhile, cook the choy sum in a large saucepan of boiling water for 1-2 minutes until just tender, then drain well. Place in a bowl with the bean sprouts and 1 tablespoon of the nam jim and toss to combine.

Step 4

Divide the vegetable mixture among plates, top with fish and drizzle with the remaining nam jim. Serve with lime wedges.
