Oven Bake: Preheat oven to 200 °C. Place portions in a lightly greased ovenproof dish. Drizzle with olive oil or brush with soft margarine and lightly season with freshly ground black pepper. Bake for 20-25 minutes. Once cooked, the fish should change from translucent to white and flake easily with a fork.
Pan Fry: Coat portions in seasoned flour (optional). Heat a little oil in a frying pan over medium heat. Fry steaks for 4-6 minutes on each side until golden brown. Remove from pan and drain on paper towel or serviette before serving. Once cooked, the fish should change from translucent to white and flake easily with a fork.
