Chickpea and cavolo nero soup

Method

1. Put the chickpeas (see tip) in a large pan of cold salted water, bring to the boil, then reduce the heat and simmer for 20-30 minutes until just tender. Drain and set aside in the saucepan.
2. Meanwhile, heat the oil in a frying pan and gently fry the pancetta until crisp. Remove with a slotted spoon and set aside. Add the onion and celery to the pan and fry gently for 15 minutes or until tender. Add the garlic and fry for a minute. Put the fried onion, celery and garlic (and residual oil) along with the pancetta in the pan containing the chickpeas.
3. Pour over the chicken stock and add the oregano and the chilli flakes. Season well and bring to a simmer, then add the cavolo nero and cook gently for 10-12 minutes. Season well. Serve bowlfuls of the chunky soup with grated parmesan sprinkled over, and dollops of soured cream and crusty bread.
