Beans, corn, scallions, bell peppers and onions are mixed together and napped with a vinaigrette dressing that has had a few niceties added: cilantro, pepper, cayenne and cumin. Toss and let sit overnight. Wonderful!
Best if cooking is started the day before serving. Boston butt is the easiest to make on a small scale. Use a shoulder or a whole shoulder (which is a shoulder plus the Boston butt) for larger crowds. The sauce skimmed off the top is very, very hot and can also be used to make terribly hot chicken wings.
