The Sicilian-style tomato sauce has tons of Mediterranean flavor, thanks to the orange peel, olives, and oregano.
Ingredients
2 tablespoons extra-virgin olive oil
1 cup chopped onion
1 cup dry white wine
1 teaspoon anchovy paste
2 14 1/2-ounce cans diced tomatoes with garlic, basil, and oregano in juice
4 6-ounce mahi-mahi fillets
1/2 cup large green olives, quartered, pitted
3 teaspoons chopped fresh oregano, divided
1 teaspoon (packed) finely grated orange peel
Country-style white bread cut into 1/2-inch-thick slices, toasted
Directions
Heat oil in heavy large skillet over medium-high heat. Add onion; sauté until translucent and beginning to brown, about 4 minutes. Add wine and anchovy paste. Boil until reduced to 3/4 cup, about 3 minutes. Add tomatoes with juice; bring to boil.
Sprinkle fish with salt and pepper. Add fish to skillet atop tomato mixture. Reduce heat to low, cover, and simmer until fish is cooked through, about 9 minutes. Using slotted metal spatula, transfer fish to plate and tent with foil to keep warm. Mix olives, 2 teaspoons oregano, and orange peel into sauce in skillet. Increase heat to high and boil until sauce is reduced and thickened, about 6 minutes. Season to taste with salt and pepper. Place 1 fish fillet on each of 4 plates. Pour sauce over and around fish, sprinkle with remaining 1 teaspoon oregano, and serve with warm toasted bread.
