Steps
- With a sharp knife, slice the tuna into thin 0.5cm pieces. Arrange on a serving platter alongside the avocado slices.
- Mix the olive oil and lime juice in a small bowl. Just before serving, drizzle the lime dressing over the tuna and avocado. Sprinkle with spring onions and season lightly with sea salt and pepper.
- Present with soy sauce for dipping and additional lime wedges, if preferred.
