Here's a sandwich that does regular burgers one better—with a surprise pocket of cheddar! "The beef patties contain additional popular toppings, including ketchup, mustard and onions," lists Janet Wood of Windham, New Hampshire. "Whenever I serve these, though, folks enjoy finding the melted cheese most."
Total TimePrep/Total Time: 25 min.
- 1/4 cup ketchup
- 1/4 cup finely chopped onion
- 4 teaspoons prepared mustard
- 2 teaspoons salt
- 1 teaspoon pepper
- 4 pounds ground beef
- 1-1/2 cups shredded cheddar cheese
