Prepare an 8 or 9-inch baking dish and lightly grease it with cooking spray. Add one layer of tomato sauce and add one layer of eggplant slices on top.
Then top with mozzarella cheese, again the sauce, and parmesan.
Repeat all the layers 1 more time finishing with parmesan cheese. Bake at 400 degrees F for 30 minutes or until the top layer becomes crispy and golden brown.
Do not cover the dish. Garnish with fresh basil leaves.
