Start frying the ground beef in a large skillet over medium-high heat.

Once the ground beef is broken into smaller pieces, stir in the mustard, brown sugar, minced onion, Worchester sauce, seasoned salt and black pepper.

Fry until browned and drain the excess grease.

Stir in the tomato soup, ketchup and water.

Turn heat to medium-low and simmer for 10-15 minutes, until thickened, stirring often.
