Arrange the fish in a pre-buttered tray. Season them with oregano and black pepper, cover with aluminum foil and bake 20 min. in a preheated 392°F (200 °C). Remove the foil and crisp the fish for another 5 min. with just the top element or on a grill.
Serve the fish with a salad of your choice, sprinkled generously with parsley.
