Black Bean Soup

1/2 lb. black beans

1 cup olive oil

1 large onion, chopped

1 clove garlic

1 Tbsp. salt

1 oz. salt pork or bacon

1/4 lb. ham bone

1/2 cup vinegar

3 green peppers, chopped

3 bay leaves

1 1/2 qts. water

Soak beans thoroughly. Fry onion, green pepper and garlic in 1/2 cup oil. Combine all ingredients except vinegar and cook over low heat until beans are tender and the liquid is thick. Add vinegar just before serving. I usually serve the vinegar separately and let each person add it to his taste.
