Mix all ingredients except for tomato sauce and oil together in a bowl until all items are mixed well.
Divide the mixture into 2 patties and form them in your hand to about the size of the mushrooms.
To prepare the mushroom, spray a baking dish, add the tomato sauce and olive oil to the pan, and add the mushrooms (washed and stem removed) into the sauce.
Add the beef patty to the mushrooms and bake at 350 degrees Fahrenheit for about 30 minutes. Then add the cheese to the top, and some chives for garnish, then bake for an additional 5 minutes to melt the cheese.
