Black Bean Soup (with the Kitchen Sink)

It’s very easy to hide a great deal of things in a pot of black beans. Good things, bad things, all kinds of things — and no one may notice. Cooked to a velvety sauce, with strange lumps that once used to be part of a bean suspended throughout, the soup is thick as tar and opaque brown-black as fudge. You don’t know what’s hiding in it.
