Ingredients

1/2 cup extra-virgin olive oil

1 large red onion, finely chopped

2 large garlic cloves, sliced

3 red bell peppers, cored, seeded, and cut into 1-inch pieces

3 yellow bell peppers, cored, seeded, and cut into 1-inch pieces

Pinch of crushed red-pepper flakes

2 canned anchovies

10 ripe plum tomatoes, diced, or 1 (35-ounce) can whole tomatoes, drained and passed through the medium disk of a food mill

1 tablespoon capers, rinsed

Coarse salt and freshly ground black pepper

4 fillets (about 8 ounces each) wild striped bass, skin on

8 slices lemon

1/2 cup extra-virgin olive oil

4 sprigs fresh rosemary

Roasted Potatoes

Preparation

Make the peperonata: In a large skillet, heat oil over medium heat; add onion and garlic, and cook, stirring, until onion is translucent, about 3 minutes. Add remaining ingredients, stirring to break up anchovies. Season with salt and pepper. Reduce the heat to a simmer, and cook, stirring occasionally, until peppers are very soft, about 45 minutes.

Preheat oven to 500 degrees. Make the bass: Place 2 lemon slices on a small rimmed baking sheet; top with a piece of bass. Repeat process with remaining lemon slices and bass. Season with salt and pepper. Drizzle evenly with oil, and top each piece of fish with a sprig of rosemary. Roast until the fish is cooked through, 10 to 12 minutes.

Serve fish over peperonata with potatoes on the side.
