1.First cook the rice, according to the manufacturer’s instructions; cool slightly.
2.Meanwhile roll salmon in combined sesame seeds and wasabi powder until coated.
3.Heat oil in a large frying pan over high heat; cook salmon for 1 minute each side or until browned but still raw in the centre. Cool for 5 minutes. Cut into thin slices.
4.Place brown rice in a large bowl with salad leaves, ginger, onion, chilli and avocado; toss gently to combine.
5.Place sauce, juice and extra oil in a screw-top jar; shake well.
6.Arrange rice salad and salmon on a platter; drizzle with dressing. Serve with lime wedges.
If you can’t find wasabi powder, use the equivalent amount of wasabi paste and spread it over the salmon before rolling it in sesame seeds. If you are unable to obtain sashimi-grade raw salmon, or prefer your fish cooked, simply cook the fish for a further 1½ minutes on each side or until cooked through.
