Savory piquillo peppers, which are also ideal for stuffing, are grown in Northern Spain, where they're roasted and packed in jars. Roasted red peppers make a delicious substitute. This combination of onions, bell peppers and capers is an outstanding topping for any roasted fish. Serve over your favorite rice.
Preheat the oven to 400°F. In a small bowl, toss together onion, bell pepper, piquillo peppers and capers and set aside. Arrange fillets, skin-side down, in a large baking dish or roasting pan. Drizzle with oil and season with salt and pepper. Top with pepper mixture and bake until cooked through, 15 to 20 minutes. Transfer halibut to plates and spoon peppers and pan juices over fish. Drizzle with vinegar and serve.
