  1. Preheat the oven to gas 3, 170°C, fan 150°C. To make the tzatziki, toss the grated apple with 1 tsp lemon juice to prevent browning. Put the apple and cucumber in a clean tea towel and wring out to remove excess water. Transfer to a bowl and add the mint, yogurt and a little seasoning. Stir to combine.
  2. Put the mackerel fillets on a lightly oiled baking tray, skin-side down. Combine the honey with the chopped thyme leaves and remaining lemon juice. Spoon the honey mixture over the mackerel fillets, season well and top each with overlapping lemon slices. Roast for 15 mins, or until just cooked through.
  3. Meanwhile, prepare the couscous according to the pack instructions. Steam the spring greens for 3-4 mins, until just tender. Serve the baked mackerel with the couscous, apple tzatziki, spring greens and a few mint leaves and thyme sprigs to garnish.

Freezing and defrosting guidelines

Only the fish can be frozen. Cook as instructed and allow to cool completely. Then transfer to an airtight, freezer-safe container, seal and freeze for up to 1-3 months. To serve, defrost thoroughly in the fridge overnight before reheating.
