Oops, I guess I hit the new thread button instead of post reply. These were all supoosed to be in the "Is it worth it to get a crockpot if we're vegetarian" thread!
Rinse two cups dry pinto beans and place in crock with water to cover plus about an inch. Add:
1 small onion, chopped and/or a leek, white and some of the green, slivered
2 or 3 cloves garlic, diced
1 med. potato, diced
1 lg carrot, sliced
about 20 crimini mushrooms, quartered
2 tsp salt
little bit of ginger puree
2 tsp dry basil
1/2 tsp black pepper
1/2 tsp dry cilantro
cook on low about 8 hours. Add can of diced tomatoes, a splash of sherry or red vinegar, and a splash of lemon juice, stir and turn up to high for about an hour.
(If you add the tomatoes at the beginning the beans won't soften properly.)
