   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.
