Green Chile Soup

1 1/2 pounds pork neck bones
2 (7 ounce) cans diced green chiles
2 pounds potatoes, cubed
28 ounces chopped stewed tomatoes
1 large sweet onion, cubed
3 stalks celery, chopped
1 teaspoon ground cumin
2 tablespoons chili powder
4 cups water

Preheat oven to 400 degrees F (200 degrees C).

Place bones into a heavy roasting pan and add enough water to cover bottom of pan. Cover pan with a tight fitting lid and cook until browned. You may need to add more water while it is cooking.

In a large stock pot, combine browned bones, chiles, potatoes, tomatoes, onion, celery, cumin, chili pepper and liquid. Simmer for 5 to 6 hours.

Remove bones from soup, remove any meat, and place meat back into soup. Serve when vegetables are tender.
