This is a wonderful, spicy recipe for Christmas leftover turkey, but equally a fantastically adaptable method to use with chicken - or indeed more vegetables (squash is excellent) - at any time of year. If you have leftover gravy from the Christmas meal, you can dilute it with water to use instead of the stock, and by all means use kidney beans instead of black, and hot smoked paprika in place of the chipotle if you prefer.
Cook the onion, celery and garlic in the olive oil with a pinch of salt for 10 minutes until soft and beginning to brown
Add chipotle paste, oregano, tomato purée, tomatoes and cocoa if using, and cook for 5-10 minutes until rich and thick. Stir in the stock and black beans, and cook for 10 minutes
Take half of the soup and blend until very smooth, then return back to the pan and stir in the meat, adding a bit more water if too thick
Heat through gently for 5 minutes and season to taste if needed
Serve topped with a dollop of sour cream, and sprinkled with the chilli and coriander.
