Chilled pea soup

Method

1. Heat a glug of oil in a large saucepan over a medium heat. Add the spring onions and cook for 8 minutes, then add the garlic and cook for 2 minutes more. Stir in the peas, then pour over the hot stock, season with salt and pepper and simmer for 5 minutes.
2. Meanwhile, roughly chop most of the basil and most of the salad leaves. After the soup has been cooking for 5 minutes, add the chopped leaves to the pan. Bring back to a simmer and cook for a further 2 minutes.
3. Remove from the heat and, using a stick blender, whizz until smooth. Stir in most of the yogurt, then put in an airtight container and chill for at least 4 hours (see Make Ahead).
4. Once chilled, season to taste and divide among 4 bowls. Top with the remaining yogurt, basil, salad leaves and a drizzle of olive oil to serve.
