Step-by-step instructions

1. 1

   Mix together the ingredients from the soy sauce down to the chilli pepper, stir well, and stand for a while for flavours to mix.

2. 2

   Put in a suitable container in a warming oven to just warm through.

3. 3

   Brush the tuna steaks with the olive oil and just sear quickly on both sides in a hot griddle pan over very high heat for rare meat -- or cook to your liking. Use salt to taste.

4. 4

   Arrange the arugula on 4 plates, top each with a tuna steak, and drizzle the citrus sauce with orange segments over each serving.

5. 5

   Serve immediately -- but can be served cold.
