1. Chop the onions, celery, carrot, herbs and garlic in a generous glug of olive oil and good sprinkle of salt. Let it stew gently until the vegetables soften and smell sweet.
2. Empty the cannellini beans into the cooked veggies and mix them into the veggies and oil. Once warmed through add the two cans of tomatoes and let it cook until the tomatoes smell sweeter.
3. Add about a litre of vegetable stock and bring up to a simmer.
4. Add all the shredded green veg and bring it back to a simmer for 5 minutes and serve straight away. A spritz of lemon sets this soup off nicely.
