Vegetarian moussaka

Method

1. Preheat the oven to 230°C/fan210°C/ gas 8. Par-boil the potatoes for 5 minutes, then drain and divide between 2 roasting tins with the aubergine, onion, garlic and peppers. Sprinkle with the herbs, drizzle with the olive oil and roast for 20 minutes, turning halfway. Add the tomatoes and cook for 5 minutes, until tender and scorched at the edges. Reduce the oven to 200°C/fan180°C/gas 6.
2. Put half the vegetables into 6 x 350ml ovenproof dishes or a 2-litre ovenproof dish. Spoon over half the passata and the feta. Top with the remaining vegetables and passata.
3. Mix the yogurt, eggs and Parmesan in a jug, then pour over the veg. Bake individual dishes for 20 minutes or the large dish for 30 minutes. Check the yogurt mix is firm before serving, garnished with thyme leaves.
