This tastes just like the mushroom and swiss hamburgers from a famous fast-food chain.
Step: 1
Mix golden mushroom soup, sliced mushrooms, and Worcestershire sauce in a saucepan over low heat and simmer while you complete the remaining steps. Stir sauce occasionally.
Step: 2
Mix ground beef with monosodium glutamate, seasoned salt, and black pepper in a bowl; form 4 patties from the ground beef and pan-fry in a skillet over medium heat until browned, about 5 minutes per side.
Step: 3
Place each burger onto the bottom of a hamburger bun and top each with a slice Swiss-style processed cheese. Spoon 1 to 2 tablespoons of sauce over the cheese, place the bun tops onto the sandwiches, and serve.
