1. Lightly grease a 9 by 13 inch casserole dish and set aside. Prepare the onions, mushrooms, olives, and mozzarella. Set in refrigerator. Prepare the sausage and set in refrigerator. Set out all seasonings.
2. Put tomatoes in blender and set to chop. Use the pulse feature. Do Not over do! Open can of tomato paste and keep handy.
3. In a large skillet over medium heat (4), heat ¼ cup of the olive oil. Put 2 eggs in a bowl with ¼ cup condensed milk and mix. Pour breadcrumbs in another bowl. Dip the eggplant in the egg mixture, then in the breadcrumbs. Add the eggplant to the skillet and cook until golden brown. Transfer to a plate with paper towels and set aside.

Add the tomatoes and their juices, 1 teaspoon Italian seasoning, black olives, mushrooms ¼ teaspoon crushed red pepper and ½ teaspoon salt. Reduce heat to medium-low and gently simmer, uncovered until the flavors marry and the sauce slightly thickens, about 20 minutes.

8. Meanwhile, put 15 ounces of ricotta cheese in a bowl and stir while pouring in whole milk to make a white sauce. The sauce should be a consistency that could be poured. Add some parsley to the ricotta white sauce.

Pour on the ricotta white sauce. Arrange the other half of the eggplant slices on top of the sauce. Place the other half of the sausage-tomato sauce over the eggplant.
