Tinned tomatoes are great for making a rich sauce, whether as the main attraction or a support act for other headline ingredients; here they’re the perfect base for loading with veg and spicing up with harissa. I often make a spin on this dish, including whatever veg I’ve got lying around and swapping new potatoes for sweet potatoes, cavolo nero for spinach or cabbage and courgette for a red pepper.
Based on 4 servings, adjust as needed.
Heat the oil in a large saucepan with a lid over a medium heat. Add the onion and fry for 8–10 minutes or until beginning to brown.
Tip in the garlic and cook for 1 minute before stirring in the courgette and cooking for around 5 minutes or until starting to soften.
Tumble in the potatoes, stir through the harissa and cook for 5–8 minutes or until the potatoes are beginning to colour.
Scatter in the chickpeas and pour in the tinned tomatoes and stock. Season well with salt and freshly ground black pepper and stir everything together, pop on the lid and simmer for 15–20 minutes or until the potatoes are tender. Check the liquid levels: the sauce should have thickened a little, but you still want plenty of juices. So, if it’s getting slightly dry, pour in a splash of hot water.
If serving with cous cous, pour it into a bowl and pour over boiling water until fully covered - you can use hot veggie stock for extra flavour. Cover with cling film or a plate and leave to soak for 10-15 minutes. Fluffy with a fork and season before serving.
Once the potatoes are tender, stir in the cavolo nero and simmer for 3 minutes.
Serve with a scattering of Parmesan. This dish goes well with some couscous (see method above) or slices of crusty bread, if you prefer.
