This is a quick, easy, and appropriate accompaniment to the preceding dish.
Place all ingredients except salt, including liquid from canned beans, in a saucepan. Bring to a boil, then reduce heat and simmer, uncovered, for 10 to 15 minutes. Purée mixture in blender or food processor, then return to pan and continue cooking over very low heat, stirring frequently, until thickened. Add salt to taste (but be careful: canned beans are usually sufficiently salty to begin with). Allow to sit for about 5 minutes, stir again, then serve.
