Grilled red snapper (or branzino) with roasted pepper relish and fennel

Instructions

1. Preheat grill to medium-high.
2. Place whole bell peppers on grill; cook, turning occasionally with tongs, until blackened all over, about 15 minutes. Immediately transfer peppers to large bowl, cover tightly with plastic wrap, and let steam until cool enough to handle, 10−15 minutes. Hold peppers one at a time under running water; rub off charred skin with your fingers. Pat peppers dry and scrape out seeds. Coarsely chop peppers.
3. In bowl, combine chopped peppers, garlic, celery, 3 tablespoons oil, the lemon juice, and 3/4 teaspoon salt; let sit, stirring occasionally. Coat fish with remaining 1 tablespoon oil and sprinkle with the black pepper and remaining 1 teaspoon salt.
4. Spray 2 large pieces of foil with nonstick spray; place 4 fillets on each piece of foil, skin side up, and poke a few holes in foil using skewer. Slide foil onto hot grill; cook fillets until golden brown on bottom, 3−4 minutes. Flip fillets; cook, skin side down, until opaque and browned, 2−3 minutes. Arrange fish on platter. Stir basil into pepper relish and spoon over fish. Sprinkle with fennel. Remove skin before eating.
5. Serving size: 1 fillet and 1/3 cup relish and fennel
