#Black beans make a nutritious and satisfying pasta topping. They go perfectly with a tasty tomato sauce and garlicky breadcrumbs.# Heat the oil gently in a saucepan. Add the carrot, onion, celery, garlic and
beans and stir gently in the oil for 5 minutes, or until the vegetables soften. Add the tomatoes and chilli or cinnamon and stir again. Heat to simmering, cover with a lid and cook over very low heat for 30 minutes, stirring from time to time. You might need to add a little reserved tomato juice to keep the sauce moist. Add salt and pepper to taste and discard the chilli or cinnamon stick.
