If you make the tomato anchovy oil a day ahead here, you can then delight in the fact that a midweek supper can be on the table within 20 minutes. The fuss-free cooking method – all hail the traybake! – plus the dialled-up flavours – all hail puttanesca! – makes such a winning combination.
Based on 4 servings, adjust as needed.
First make the tomato anchovy oil. Put all 85 mls of oil (if cooking for 4), anchovies and tomato paste into a small sauté pan and place on a medium heat. Once the mixture starts to simmer, cook for 5 minutes, stirring from time to time. Add the chilli flakes and coriander seeds and cook for another minute, until fragrant. Remove from the heat and add the garlic, 2 preserved lemons (if cooking for 4) and maple syrup. Stir to combine, then set aside to cool.
Preheat the oven to 220°C fan.
Place the beans, spring onions and tomatoes on a large, parchment-lined baking tray. Drizzle over 3 tablespoons of your tomato anchovy oil (if cooking for 4) along with a pinch of salt and a good grind of pepper. Toss to combine and place in the oven for 12–13 minutes, until the beans and tomatoes are starting to soften and taking on a little colour. Meanwhile, arrange the salmon fillets on a plate and, using a spoon, drizzle the remaining tomato anchovy oil (as well as all the solids) evenly over the fillets. Once the beans and tomatoes have had their time in the oven, nestle the salmon fillets among them and bake for a further 8 minutes. Set aside for 5 minutes, out of the oven, to rest.
While the salmon is baking, mix all the ingredients for the salad in a bowl. Kamalata olives, capers, remaining preserved lemon, basil, parsley, lemon juice and the remaining 2 tbsps of olive oil and season with a good grind of pepper. Spoon half the salsa over the salmon and serve the fish warm (or at room temperature, which works just as well), with the rest of the salsa in a bowl on the side.
Serve with rice, if you wish.
