  Heat the oven to 400 degrees F.  Cook and stir the meat in a large skillet 
  until brown.  Drain off the excess fat.  Stir in half of the tomato sauce 
  and the oregano leaves into the meat mixture.  Heat to boiling then reduce 
  the heat and simmer, uncovered, for 10 minutes.  While the meat mixture is 
  simmering, mix the baking mix, egg and the milk.  Measure out 3/4 cup of 
  the batter and set aside.  Spread the remaining batter in a greased baking 
  pan 9 X 9 X 2-inches.  Pour into the remaining tomato sauce over the 
  batter, spreading evenly.  Layer 4 slices of the cheese, the meat mixture, 
  the mushrooms and the remaining cheese on top of the batter and tomato 
  sauce.  Spoon the reserved batter on the top of the cheese.  Sprinkle the 
  batter top with the grated Parmesan cheese and bake, uncovered, until it is 
  golden brown, 20 to 25 minutes.  Cool for 5 minutes before cutting into 
  squares and serving.
