Grilled Mushroom Swiss Burgers

INGREDIENTS (Nutrition)

• 1 1/2 pounds lean ground beef
• 1/2 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

1. Prepare a grill for medium heat. Lightly oil the grate.
2. Divide the ground beef into 6 patties. Season with meat tenderizer, salt and pepper. Set aside.
3. Melt the butter in a skillet over medium heat. Add the mushrooms and soy sauce; cook and stir until browned. Set aside and keep warm.
4. Grill the patties for about 6 minutes per side, or until cooked through. Divide the mushroom mixture evenly amongst the burgers and top each one with a slice of Swiss cheese. Cover the grill for about 1 minute to allow the cheese to melt. Remove from the grill and serve on hamburger buns.
