1. To make the pesto, place the pine nuts, fresh basil leaves and garlic in a food processor and blend to a rough paste. Add the Parmesan and, with the blades running, gradually add the oil.

2. Season the mackerel well with plenty of salt and freshly ground black pepper and cook on a medium­-hot barbecue for about 12-15 minutes, turning once.

3. Meanwhile, heat the olive oil in a large, heavy-based saucepan and sauté the chopped onions until soft and golden brown.

4. Stir the chopped tomatoes into the contents of the saucepan and cook for 5 minutes. Serve the fish on top of the tomato mixture and top with a generous spoonful of the pesto.
