1 large firm eggplant
1/2 cup all-purpose flour
2 eggs, beaten or egg substitute equivalent
1/2 cup dry bread crumbs
8 oz. package mozzarella cheese slices
24 oz. jar spaghetti sauce
1/2 tsp. dried oregano
1/2 cup grated Parmesan cheese
Preheat oven to 350 degrees. Peel eggplant and cut cross-wise into one-half inch rounds. Salt eggplant slices on both sides and let sit for 20 minutes. Rinse off bitter juices and pat dry with paper towel. Sprinkle half of flour, eggs, and bread crumbs into three separate plates. Dip eggplant slices progressively in flour, eggs, and then bread crumbs. Add more of these ingredients as needed until all eggplant slices are coated.
Arrange eggplant rounds in greased baking pan and bake until fork goes through and slices are tender, about 15 minutes. Flip over halfway through cooking time. Remove from oven when done.
Spread thin layer of spaghetti sauce on bottom of greased 9x13x2 inch baking dish. Arrange half of eggplant slices over sauce, then cover with half of mozzarella cheese slices. Add another layer of sauce, eggplant, and mozzarella. Top with remaining sauce. Sprinkle with oregano and Parmesan cheese. Bake until heated through and bubbly, about 20 minutes. Serves 6 to 8.
