Preheat the oven to 425°. In a large baking dish, season 4 flounder fillets with salt and pepper. Mix the 3/4 c freshly grated parmesan cheese with the 1/2 c coarse fresh bread crumbs, 4 tbsp melted butter and 2 tbsp olive oil and sprinkle over fish. Bake for 15 min or until fish is cooked and the topping is golden. Let stand for 5 min before serving.
