PREPARATION:
- Peel off and discard thin slice from 2 sides of eggplant. Cut eggplant, zucchini and summer squash into very thin (1/8- to 1/4-inch) horizontal slices; set aside.
- Heat large nonstick skillet over medium-high heat. Add turkey sausage; cook 8 to 10 minutes or until sausage is cooked through, stirring occasionally to break up sausage. Remove sausage and drain excess fat from skillet. Add bell peppers and mushrooms to skillet; cook and stir 3 to 4 minutes or until vegetables are tender. Return sausage to skillet. Add tomatoes, tomato sauce, basil, oregano, salt and pepper. Cook and stir over medium-high heat 1 to 2 minutes or until mixture is heated through; set aside.
- Preheat oven to 375°F. Layer 1/3 of eggplant, zucchini, and summer squash in 13X9-inch nonstick baking pan. Spread half of ricotta cheese over vegetables. Top with 1/3 of tomato sauce mixture. Sprinkle 1/2 of mozzarella cheese over top. Repeat layers once more, ending with final layer of vegetables and tomato sauce mixture. Sprinkle with Parmesan cheese; cover pan with foil. Bake 45 minutes. Remove foil; bake, uncovered, 10 to 15 minutes or until vegetables are tender. Cool 10 minutes before cutting.
