Step by step preparation 


  • 1 lb ground beef
  • 1 teaspoon salt
  • 1 teaspoon black pepper
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 4 large yellow onions, sliced
  • 4 slices Swiss cheese
  • 4 hamburger buns
  • 2 tablespoons butter
  • 2 tablespoons olive oil
  • 1 tablespoon Worcestershire sauce
  • 1 tablespoon balsamic vinegar
