Method
- 1
Keep the tuna in the fridge until the moment you need it. Toast the sesame seeds in a dry pan for 1 minute, until golden, and tip them onto a plate.
- 2
Mix the lime juice and tamari in a glass or ceramic bowl. Add the tuna and turn it gently. Leave in the fridge for 10 minutes, no longer, so the outside turns paler but the middle stays deep red.
10 min - 3
Soak the red onion in cold water for 5 minutes, then drain.
- 4
Drain off half of the lime liquid from the tuna. Add the cucumber, chillies, onion, coriander and olive oil and toss gently.
- 5
Fold in the avocado, scatter with the sesame seeds and serve straight away in small bowls.
