This is Austerity Soup. The recipe: as with any good hearty soup, start with the Holy Quadernity of onion, celery, carrot and leek. Add chopped broccoli stem, the green tops of leeks and spring onions, the outer leaves which surround cauliflower, the tops of carrots, turnips and beetroots. Add any vegetables which are getting a bit past their best, and sweat until soft and sweet. Add a handful of frozen peas (protein content 👍) with stock or bouillon and water. Simmer for 10 minutes then blend smooth and add seasoning to taste.
This version has fried chorizo and oil on top, because Julien believes any soup is improved by a bit of porkiness. In the case of green soup, I would have to agree, though it does perhaps reduce the thriftiness of this soup!
