Step 1Heat the oven to 400 degrees.
Step 2Combine the tomatoes, garlic, capers, basil, 2 tablespoons of olive oil, 1/4 teaspoon of salt and 1/4 teaspoon of pepper in a bowl and set aside.
Step 3Rinse the fish and pat dry. Lightly sprinkle with salt and pepper and dredge in flour. Heat a large skillet and add the remaining olive oil. Add several filets to the pan and cook 1 minute per side, then remove. Repeat with the remaining filets. Place the fish in one layer in a large roasting pan. Spread the tomato mixture over the top and bake until the fish flakes with a fork and is cooked through, 5 to 7 minutes.
