1. Heat 2 tablespoons of oil in a large saucepan over a medium heat.
2. Peel, finely slice and add the onion along with the curry paste, mix well, then cook for 10 minutes, or until the onion is soft and golden, stirring occasionally.
3. Finely chop the chilli, then peel and finely grate the ginger. Pick the coriander leaves and finely slice the stalks. Chop the potatoes into 2cm chunks.
4. Add the chilli, ginger, coriander stalks and potato to the softened onion. Drain and tip in the chickpeas, then cook for 5 minutes.
5. Roughly chop and add the fresh tomatoes (if using) or tip in the tinned tomatoes. Add 200ml of water and bring to the boil.
6. Reduce the heat to a simmer, then cover and cook for 10 to 15 minutes.
7. Remove the lid, then cook for a further 30 to 45 minutes, stirring occasionally, or until the sweet potato is cooked through and the sauce thickened.
8. Stir in the coconut milk and cook for a couple of minutes, then stir in the spinach and cook until wilted.
9. Scatter over the coriander leaves, then serve with rice.

Although the recipe says sweet potatoes you can use normal ones, you could also add more vegetables if you want. We’ve tried it with aubergine, cauliflower, peppers and it’s been nice every time. This recipe also makes a huge amount so it’s great for freezing or eating the next day as left overs. If you like curry and vegetables this is definitely one you should try out.
