Season the cod, then place on a lightly oiled baking sheet. Rub 1 tablespoon of the oil over the top of the fish.
Mix together all the remaining ingredients. Press on top of each fish fillet, then drizzle over the remaining oil. Place in a preheated oven, 200°C (400°F), Gas Mark 6, for 12–15 minutes until the fish is lightly crisp and cooked through. Serve with potatoes and a tomato salad.
