Black bean soup

Not a precise recipe, but a good flavour combination.

Saute celery, carrot and onion with oil and plenty of cumin, smoked paprika, black pepper, plus chilli flakes to taste. Add 2 veg (or any) stock cubes made up with a litre of water, a generous dollop of tomato puree, and a splash of wine/cider vinegar. Add 2 tins of black beans, drained and rinsed. Simmer until carrots and beans are soft, then puree half of the soup.
