Fry the onion and celery in the olive oil until soft and golden. Stir in the smoked paprika and cook for 1-2 minutes.
Add the rest of the ingredients and bring to boil. Simmer gently for about 10 minutes, until slightly thickened.
Adding a combination of Bonne Maman Salted Caramel and paprika to the beans adds a rich, sweet smoky flavour. If you make these the night before, they'll taste even better - just keep them in the fridge until you're ready to reheat them.
