Place beans and water in a large pot. Soak overnight.
Bring to a boil, cover, reduce heat, and cook until
tender, about 2 to 3 hours. Add onion, yams, carrot,
celery, and leek. Cook for 30 minutes. Add remaining
ingredients. Cook an additional 30 minutes.
Serving Suggestions: Pour into individual bowls or
over any whole grain. Also good as a topping for
potatoes or whole-wheat bread.
Helpful Hint: This dish can easily be made in a slow
cooker. Add all ingredients at once and cook on the
high heat setting for 8 to 10 hours. Be sure to soak
the beans overnight before you begin.
