How to Make It
Preheat the oven to 425°. In a very large roasting pan, toss the potatoes, tomatoes, olives and basil with 1/2 cup of the olive oil. Season with salt and pepper.
Make 3 shallow slashes in both sides of each fish. Rub each fish with 1 tablespoon of the olive oil and season with salt and pepper. Set the fish in the roasting pan, tucking them into the vegetables. Roast for about 40 minutes, until the vegetables are tender and the fish are cooked through.
Meanwhile, in a small skillet, toast the pine nuts in the remaining 1 tablespoon of olive oil over moderate heat, stirring, until golden, about 3 minutes. Spoon the pine nuts over the fish and vegetables in the roasting pan and serve right away.
