Pin-bone the fish, remove any scales and then season with salt and pepper. Add some lemon zest and a few sprigs of thyme. Place on a baking tray and bake for 7-8 minutes.
Pick and chop the herbs and then mix through the yogurt.
Peel and dice the shallot. Break the feta cheese in to small pieces. Separate the broccoli and cook for 2 minutes in salted boiling water. Roast the pine nuts in the oven at 180'c for 6 minutes. Pick the mint and chop.
Add a splash of olive oil and the 3 pinches of salt to couscous and stir well. Bring the 300ml of water to boil pour over the couscous and cover with cling film. Leave for 5 minutes. Break the couscous up with a fork and then fold in the feta, broccoli, pine nuts and mint. Check the seasoning. Wash and dry the spinach. Peel and mince the garlic.
Heat a frying pan until hot and add the olive oil. Cook the spinach with the garlic and a pinch of salt. Once the leaves have wilted, squeeze on the lemon juice and keep warm.

«Be careful not to overcook the fish. When the thickest part of the fillet is white it is cooked.»
