(My favorite version of this…from La Cantinita restaurant, Arlington, Virginia)
1 lb black turtle beans
1 large onion, chopped
2 green pepper, chopped
4 cloves freshly ground garlic
2/3 C extra virgin olive oil
1/2 t cumin
1/2 t oregano
2 bay leaves
about 2 t salt
In a large pot, put the beans and cover with approximately 10 cups of water. Soak overnight with one green pepper. When ready to cook, boil beans until tender to the touch. Time will vary with the beans. You may need to add water to maintain the water level to the top of the pot. When beans are slightly tender to the touch, add salt to taste. In a frying pan add the olive oil and the remaining ingredients. Saute until the green pepper and onion are tender. Add to the beans and continue cooking until the beans have thickened. If additional thickening is desired, remove 1 cup of beans, mash thoroughly, and return to the pot.
