“Spinach and walnuts are a quick and tasty filling for delicate flounder fillets. Chopped tomatoes strewn over the top make a pretty garnish. Make it a meal: Serve with Garlicky Green Beans and bulgur.”


    • 2 teaspoons extra-virgin olive oil, plus additional for preparing baking dish
    • 1 10-ounce package fresh spinach, stemmed and washed or 10-ounce package frozen chopped spinach, thawed
    • 2 tablespoons finely chopped walnuts
    • Salt & freshly ground pepper, to taste
    • 8 small Pacific flounder fillets (about 1½ pounds total)
    • 2 fresh plum tomatoes, seeded and chopped


  • 1 Preheat over to 375°F. Lightly coat an 8-by-11-inch baking dish with oil or coat with cooking spray.
  • 2 If using fresh spinach, coarsely chop and shake in a colander to remove excess water. If using frozen spinach, squeeze it dry.
  • 3 Heat oil in a large skillet over medium-high heat. Add walnuts and stir until lightly toasted, about 1 minute. If using fresh spinach, add to the pan, in batches if necessary, and toss until just wilted, about 2 minutes. If using frozen spinach, add and toss until heated through. Season with salt and pepper.
  • 4 Place about 2 tablespoons of the spinach mixture over one half of each flounder fillet. Fold the other half over. Season with salt and pepper. Transfer the stuffed fillets to the prepared baking dish and scatter tomatoes over the top.
  • 5 Cover with foil and bake until the fish is opaque in the center, 15 to 20 minutes.
