How to make it
Soak beans overnight in water to cover, changing water once; drain.
When beans are ready, saute onion, garlic, green chiles and tomatoes in oil in a large soup pot or Dutch oven over medium-high heat. Add water or stock and ham hock; bring to a boil. Add beans, coriander seed, bay leaf and dried chiles. Continue to gently boil for 30 minutes, then lower heat, cover and simmer for three to four hours, until beans are tender. Season with salt and pepper to taste.
