about 2 hours. Drain, reserving the liquid. Preheat the oven to 350 degrees. Saute the onion, celery, green pepper, and garlic in the 1/2 cup water for 10 minutes. Remove from heat and add the cooked beans, 1 1/2 cups bean-cooking liquid, and seasonings. Pour into a casserole dish and bake for 1 hour.

Hint: Mash or grind up the leftovers for a delicious cold sandwich spread.
