Mama's Sloppy Joe

1 stick of margarine
2 chopped onions
2 teaspoons of salt
3 teaspoons of dry mustard
2  8 ounce cans of tomato sauce
1 1/2 cups grated cheese
2  cans of cream corn
4 pounds ground beef
2 teaspoon garlic salt
1 teaspoon black pepper
2 tablespoons vinegar
1 1/2 tablespoons Worcestershire sauce

Melt butter, add ground beef, onions, garlic salt, pepper and dry mustard.  Stir until meat is brown.
Add vinegar, tomato sauce, Worcestershire sauce, cheese and corn.  Simmer 15-30 minutes.  Serve on warm buns.

The way Mama would always serve it was delicious.  She would open the buns and lightly butter them.  She would toast the buns.  Then she would spread mayonnaise on each piece of the buns.  She would then top the Mao with a slice of tomato.  Season the tomato with a little salt and pepper. Then she would spoon the Sloppy Joe over the tomato and serve it open face.
