Roasted pepper & mixed bean stew with harissa

Soak the beans overnight in cold water. Drain and place in a pan with plenty of fresh, cold water. Bring to the boil and cook for 10 minutes then reduce the heat and simmer for up to 2 hours until all the beans are tender, topping up with boiling water as needed.

Meanwhile, preheat the oven to 200 degrees C, gas mark 6. Toss the sweet potatoes with the chopped preserved lemons, harissa and cumin seeds and arrange in a roasting tin. Roast for 30-35 minutes, stirring occasionally until browned and tender.

Heat the olive oil in a large saucepan. Add the onion, garlic and peppers and cook over a medium heat for 5-6 minutes until softened. Add the stock, drained beans, apricots and seasoning and simmer, covered, for 10 minutes, stirring occasionally until the peppers are tender.

Add the sweet potatoes with all the contents of the roasting tin and simmer for a further 5-6 minutes until the sauce has thickened, if needed. Serve scattered with more chopped apricots and mint with soured cream on the side. A green salad and warm tortillas make tasty additions too.
