1 1/2 pounds ground chuck or sirloin
1/4 teaspoon salt
1/4 teaspoon ground black pepper
1/2 teaspoon Worcestershire sauce
1 large egg
4 slices Cheddar cheese
1 large onion , sliced in rings
4 onion rolls, halved and toasted
1 large tomato, sliced
4 lettuce leaves
4 dill-pickle chips
In a medium bowl, mix ground beef, salt, pepper, Worcestershire sauce, and egg. Use your hands to form 4 equally sized patties.
Cook burgers and onions:
In large skillet, cook patties over high heat, about 4 minutes for medium or 5 minutes for well done, turning once midway through. Place 1 slice cheese atop each burger and cook 1 more minute. Remove patties from skillet and place on wire rack. Reduce heat to medium, add onions, and cook, stirring occasionally, until golden brown, about 6 minutes. Remove skillet from heat.
On bottom half of each roll, place 1 burger and top with tomato, lettuce, pickles, and onions. Cover with top of roll. Serve with ketchup and American Frites.
