Easy fish tagine

Method

1. Whizz the marinade ingredients in a mini food processor or grind in a mortar and pestle until smooth. Rub half over the cod, cover and chill for between 20 minutes and an hour.
2. Meanwhile, boil the potatoes in a pan of salted water until tender, drain, then cut in half lengthways.
3. In a shallow casserole over a low heat, fry the garlic in the oil for 1-2 minutes. Add the peppers and cook for 5 minutes, then add the tomatoes and cook for a further 2 minutes. Stir in the remaining marinade and the vegetable stock. Season well.
4. Place the potatoes in a big non-stick frying pan with a lid. Top with half the tomato mixture, then with the fish, then add the remaining tomato mixture. Scatter over the olives, cover and cook over a medium-high heat for 10-12 minutes until the fish is just cooked through. Garnish with lemon wedges and coriander to serve.
