  1. Preheat the oven to gas 8, 220ºC, fan 200ºC. Line a baking tray with foil and grease with a little oil.
  2. Put the torn bread, parsley, dill, half the thyme and some seasoning in a food processor. Pulse to fine breadcrumbs and tip onto a shallow plate.
  3. Put the mackerel fillets on the lined tray, skin-side down. Pour the lemon juice over the fillets, then press each fillet firmly into the breadcrumb mixture to coat.
  4. Place the mackerel and asparagus on the lined tray. Drizzle over 1 tsp of the olive oil and bake for 12-15 mins until the breadcrumbs are crisp and golden brown.
  5. Meanwhile, for the mash, heat 1 tsp oil in a medium saucepan. Cook the garlic over a low heat for 1-2 mins until fragrant. Add the cauliflower and fry for 4-5 mins until just beginning to soften. Add the remaining thyme and the stock and bring to a simmer. Cook over a low heat for 10-12 mins until soft. Reserve 50ml of the stock, then drain. Tip the cauliflower and a small splash of the liquid into the food processor and pulse until smooth. Return to the saucepan, stir through the lemon zest and keep warm.
  6. To serve, divide the cauliflower mash between 2 plates and top each with 2 mackerel fillets and the asparagus.
