I came up with this after reading a tip from a can of refried beans. I first made my chicken version and then thought it would be great with black beans instead of the meat. So easy to put together and a delicious soup.
Combine tomatoes, broth, beans and corn in medium saucepan. Stir together and bring to a boil. Reduce and bring to a simmer till heated through. Turn off heat and stir in the cilantro. Top each bowl of soup with cheese and crushed tortilla chips. (I use up the crushed chips from the bottom of the bag.).
