Instructions

1. Rub the dirt off the new potatoes, then cook them in lightly salted water until tender for about 10-15 mins.
2. Meanwhile, mix the soy sauce, vinegar and oil, then rub the fish with it. Heat a griddle pan and grill the fish for 2-3 minutes on each side. Set aside.
3. Finely chop the spring onions and slice the radishes. Cut the cucumber in half, scoop out the soft flesh. Cut the cucumber into small cubes. Cut the pepper or chilli into tiny cubes too.
4. Mix the dressing, taste and adjust it to your liking.
5. Shred the fish into chunks.
6. Drain the cooked potatoes and put them in a mixing bowl. Scatter the chopped vegetables and herbs on top, then pour over most of the dressing. Combine carefully.
7. Arrange the fish pieces on top, then drizzle with the remaining dressing. Season with ground pepper.
