To make the Sloppy Joes, combine 1 pound ground beef, two to three chopped celery stalks and a chopped onion to a skillet. Cook until the meat is browned and drain off the fat. Add in one 8 ounce can tomato sauce, 1/4 cup ketchup, 1/4 cup barbecue sauce, 1 tablespoon brown sugar and 1 teaspoon dry mustard, along with salt and pepper, 1 tablespoon Worcestershire sauce and 1 tablespoon vinegar. Cover and simmer for 15 to 20 minutes, stirring every once in a while. If the mixture is not thick enough, uncover the skillet and let some of the moisture evaporate.
Serve the Sloppy Joes on toasted rolls with coleslaw and French fries. To turn this recipe into a Pizza Joe, substitute an 8 ounce can of pizza sauce for the tomato sauce. Omit the barbecue sauce and use an extra 1/4 cup ketchup. Serve the Pizza Joes on toasted buns with shredded mozzarella cheese. To make a spicier version of the original recipe, use a spicy barbecue sauce.
