This is the type of food I love to cook on a weekday evening when not rushing to get dinner on the table. There is little preparation for something absolutely delicious - most of the effort is done by the heat of the oven. This harissa roast seabass recipe gives bold fresh flavours, with just one baking tray to wash up. The preserved lemons caramelise to a salty sweetness, the garlic becomes rich and soft; allowing oven time makes all the ingredients sing. Finally the salsa verde adds some welcome green acidity.
