Put all the dressing ingredients in a jar with ¼ tsp each of salt and black pepper. Seal, then shake vigorously and set aside for 5 minutes.
Put the onion in a shallow bowl, pour over the dressing (removing the garlic) and leave to marinate – this removes some of the onion’s astringency. Meanwhile, heat the oven to 200C/fan 180C/gas 6. Heat the rolls in the oven for 5 minutes until lightly toasted.
Spoon a couple of teaspoons of the dressing over the fleshy side of the mackerel fillets, then season generously with salt. Heat 2 tbsp of olive oil in a frying pan over a medium-high heat. Fry the fillets, skin-side down, for 3-4 minutes. Once the skin has begun to crisp up, flip the fillets and cook for another 1-2 minutes on the other side until just cooked through. While the fish is cooking, put the mint, carrot and rocket in the bowl with the onion and toss well.
When the mackerel is ready, transfer the fish to a plate lined with kitchen paper and begin assembling the sandwiches. Drizzle the cut sides of the toasted rolls with extra-virgin olive oil, then layer on the mackerel, followed by the tomatoes with a pinch of salt, the carrots, then a couple of teaspoons of the dressing. Put on the tops of the rolls and serve.
