1 egg, beaten
A dash of Lawry’s seasoning
Salt and pepper to taste
1 pack of sliced mushrooms
1 medium onion, sliced
1 pack of Mozzarella or Swiss cheese slices
Preheat the oven to 350 degrees Fahrenheit. In a large bowl, gently combine the ground beef, egg, Lawry’s seasoning, salt, and pepper. Be careful not to over-work the beef. Shape it into hamburger patties. Press your thumb into the center of each patty to form a depression. Chill for 10 minutes. Meanwhile, cook the mushrooms and onions over medium heat until the onions are translucent, about 5 minutes. Remove them from the heat. Cook the burger patties in a pan over heat on each side until browned, about 2 minutes. (They don’t need to be cooked through since they will cook further in the oven.) Transfer the patties into a 9×13-inch baking dish and top with the sauteed mushrooms and onions. Top each patty with 1-2 slices of cheese. Bake for 10 minutes or until the cheese is melted.
