Prepare one pound of black beans according to package directions. Remove but save the liquid. Combine beans with coconut milk, salsa, and soup base. Add vegetables. Simmer low for about a half hour, adding water as needed to make a thick soup. Add salt and pepper to taste. You can blenderize 1/3 of the soup to thicken the broth, or leave it all chunky. This is delicious as is, or serve with plum salsa.
