Fish fillets cooked in a tomato-wine sauce are the main attraction for a healthy 30-minute meal.
Heat oil in a large nonstick skillet over medium-high heat. Add onion, red pepper and garlic. Cook about 6 minutes, until softened, stirring so garlic does not burn.
Stir in tomatoes, wine, capers, olives, lemon zest and juice, oregano, salt and pepper. Bring to a boil. Add fish and cook, covered, over medium-low heat for about 8 to 10 minutes or until fish flakes easily. Gently turn fish halfway through cooking.
Serve with plain couscous and green beans, if desired.
