Preheat oven to 350 degrees.
Coat a baking dish with half of the oil. In a large bowl, combine next 9 ingredients (bell pepper through oregano); blend well.
Place a layer of eggplant slices in a prepared baking dish then pour half of the tomato mixture over the top. Layer more eggplant, then more sauce; repeat until eggplant and sauce mixture are gone.
Top with Mozzarella cheese and bake, uncovered, for 50 minutes to 1 hour or until hot and bubbly.
