Sweet Potato & Bean Soup

(Serves 4)

Ingredients

• 1 kg orange-fleshed sweet potatoes
• 1.2 ltrs boiling water or vegetable stock
• sea salt and pepper
• 400 gm can white beans (haricot or cannellini), drained and rinsed
• 1 tsp good curry powder, or more
• 80 gms low-fat yoghurt
• pinch paprika
• 2 tbsp coriander or parsley leaves

Method

Peel the sweet potatoes, cut into small cubes and put into a pan. Add the boiling water or stock, sea salt and pepper and bring to the boil. Simmer for 15 minutes or until the sweet potato is soft.

Add half the beans and the curry powder, stirring well, then whiz in a food processor in batches, being careful not to overfill the bowl.
