Step 4

Put 1 mug of quinoa and 2 mugs of boiling water into the medium pan with a pinch of sea salt and the lemon half, then pop the lid on and stir every now and again.

Step 6

On greaseproof paper, score the mackerel on both sides at 2cm intervals down to the bone. Rub all over with salt, black pepper and the ground coriander, then put into the large frying pan with 1 tablespoon of olive oil.

Step 8

Slice the tomatoes any way you like and arrange on a large board or platter, then finely slice and sprinkle over the chilli.

Step 10

Strip the rosemary leaves over the fish, then crush and add the whole garlic cloves. Turn the fish when golden (roughly 4 to 5 minutes on each side).

Step 12

When the quinoa is cooked (after roughly 10 minutes), drain it and use tongs to squeeze over the lemon juice, then spoon the quinoa into the centre of the tomatoes.

Step 14

Drizzle with 2 tablespoons of extra virgin olive oil and the balsamic, and a pinch of salt and pepper. Lay the crispy fish on top.

Step 16

Mix the yoghurt and horseradish together and dollop it over the fish. Pick over the basil leaves and serve.
