Black Bean Soup

I have found a couple of great tasting black bean soup recipes from the forksoverknives.com site. 

Mexican Black Bean and Corn Soup
I've used regular tomatoes and salt and bottled lime juice and it turns out great.

Black Bean and Salsa Soup
This recipe is so quick, simple, & delicious!
Be sure to use a good quality salsa.   I omit the extra hot sauce as the salsa I use is spicy enough.  I have been using canned no salt added corn (drained) for convenience.

Mexican Chowder
Finally, this one isn't a traditional black bean soup... but rather a Mexican chowder, but also really tasty.   Again, for convenience, I use bottled lime juice.
