What You'll Need

  • 2 tablespoons butter, divided
  • 1 cup finely chopped onion
  • 1/2 cup diced yellow or red bell pepper
  • 1 clove garlic, minced
  • 1 pound fresh spinach, chopped
  • 2 pounds flounder fillets
  • 2 cups diced tomatoes with juice or 1 can (14.5 ounces) petite diced tomatoes
  • 1/4 teaspoon dried leaf basil
  • salt and pepper, to taste

How to Make It

  1. Preheat oven to 350 F.
  2. Melt 1 tablespoon of the butter in a skillet over medium-low heat, cook the onions and bell pepper in butter until tender; add garlic and cook for 1 minute longer. Remove the onion and garlic to a plate.
  3. Add 1 more tablespoon of butter to the skillet and place over medium heat. Add the spinach, a little at a time, until wilted. Cover and cook for 4 to 5 minutes. Drain well.
  4. Place a fish fillet on a plate; spread with the cooked spinach and sprinkle with some of the cooked onion and garlic mixture. Roll up and place in a shallow lightly buttered baking dish, seam-side down. Repeat with remaining fillets.
  1. Combine the diced tomatoes with the basil and remaining onion and garlic mixture; taste and add salt and pepper, as needed.
  2. Spoon the tomato mixture over and around the stuffed fillets.
  3. Bake in the preheated oven for about 20 minutes, or until fish flakes easily with a fork.
