A good Sloppy Joe should be just that, sloppy. A little sweet with a little heat, this is a sandwich better enjoyed with a fork and knife. This method reduces the onion (especially once cooked) to a soft pulp, imparting plenty of flavor but little texture. For the savory notes, a blend of smoked paprika, chili powder, yellow mustard and cumin provide deep, smoky flavors. These are balanced by the sweetness and acidity of the tomatoes and vinegar. Adding pickled hot or sweet peppers (such as jalapeno or Peppadew) offers superior flavor. And by tossing them in the processor with the onions, their flavor is uniform. If for some reason there are leftovers, consider tossing them with warm pasta for an amazing second-day dish.
