Ingredients
1 ½ pounds lean ground beef
½ teaspoon seasoned meat tenderizer
salt and pepper to taste
2 teaspoons butter
2 (4 ounce) cans sliced mushrooms, drained
2 tablespoons soy sauce
4 slices Swiss cheese
6 hamburger buns
Directions
Preheat an outdoor grill for medium heat and lightly oil the grate.
Divide ground beef into 6 equal-sized patties; season with meat tenderizer, salt, and pepper. Set aside.
Melt butter in a skillet over medium heat. Add mushrooms and soy sauce; cook and stir until browned. Set aside and keep warm.
Grill patties on the preheated grill until cooked through, about 6 minutes per side. An instant-read thermometer inserted into the center should read at least 160 degrees F (70 degrees C).
Spoon mushroom mixture evenly on top of patties on the grill; top each one with a slice of Swiss cheese. Cover the grill until cheese melts, about 1 minute. Remove patties from the grill and serve on hamburger buns.
