Pour a little of the vegetable stock into a large saucepan and add the onion, celery and pepper.
Saute over a low heat for about 5 minutes, or until the onion translucent.
Drain the beans and rinse with cold water. Add to the vegetables and stir to combine.
Sprinkel over the spices and mix well with a wooden spoon. Then slowly pour on the stock, stirring all the time.
Cover and bring to the boil, then turn down the heat and simmer for 30 minutes over a low heat.
Serve sprinkled with fresh coriander
If you want to make this thicker and more like a stew, simply reduce the amount of stock.
