2 tbsp. butter
1 tsp. cornstarch
1/3 c. finely chopped onion
1/2 tsp. salt
3 c. shredded sharp Cheddar cheese (3/4 lb.)
1 can (10 1/2 oz.) condensed tomato soup, undiluted
1 tsp. prepared mustard
1/2 tsp. Worcestershire sauce
1 loaf white bread, cubed

Turn on heat to medium, melt butter. Add onion and stir until the onion becomes soft. Stir in salt and cornstarch, then the tomato soup. Heat, stirring frequently. Reduce the flame to low and add mustard, Worcestershire sauce and cheese, stirring until the cheese melts. Spear bread cubes on fondue forks and dip into fondue, giving a good stir each time.
