Iowan Loose-Meat Sandwiches

In a skillet (preferably cast iron), melt shortening over medium heat and sprinkle salt across the bottom. Add ground chuck and break up into small crumbles while cooking. Add chopped onion and keep working to break up meat. When meat is browned, drain off any fat. Add mustard, vinegar, sugar, and just enough water to barely cover meat in the pan. Cook, at a simmer, until water is all cooked out, about 15-20 minutes. Adjust salt and pepper to taste.

Heat your hamburger buns - they're traditionally steamed for loose-meats, or you can use a microwave. When buns are warm, spoon on the loose-meat and add yellow mustard and dill pickle slices.
