Place roast in large Dutch oven, and sprinkle with salt; add water to cover, and bring to a boil. Cover, reduce heat to medium, and cook 2 hours or until tender, adding more water as needed after 1 hour.
Stir together tomato sauce and next 10 ingredients in a large saucepan; bring to a boil. Reduce heat to low, and simmer 1 hour, stirring occasionally.
Remove roast from Dutch oven, and let stand 10 minutes before serving. Shred or slice meat, and serve with hamburger buns and sauce.
Note: For testing purposes only, we used Heinz Chili Sauce.
