Turkey 'n' Squash Lasagna Recipe

With a sharp knife, pierce spaghetti squash 10 times. Place on a microwave-safe plate; microwave on high for 5-6 minutes. Turn; cook 4-5 minutes longer or until fork-tender. Cover and let stand for 15 minutes. Cut squash in half lengthwise; discard seeds. Scoop out squash, separating strands with a fork; set aside. In a large saucepan, cook turkey and onion in 1-1/2 teaspoons oil over medium heat until meat is no longer pink. Add garlic; cook 1 minute longer. Drain. Stir in the tomatoes, tomato paste, parsley, sugar and seasonings. Bring to a boil. Reduce heat; cover and simmer for 30 minutes. In a small bowl, combine the egg, ricotta and 3/4 cup Parmesan until blended. In a small skillet, saute zucchini in remaining oil until crisp-tender. Spread 1-1/2 cups meat sauce into a 13-in. x 9-in. baking dish coated with cooking spray. Layer with three noodles and half of the zucchini, spaghetti squash and ricotta mixture. Sprinkle with 1-1/2 cups mozzarella and half of remaining sauce. Top with the remaining noodles, zucchini, spaghetti squash, ricotta mixture and sauce (dish will be full). Place dish on a baking sheet. Bake, uncovered, at 350 ° for 45-55 minutes or until edges are bubbly. Sprinkle with remaining mozzarella and Parmesan cheeses. Bake 5 minutes longer or until cheese is melted. Let stand for 10 minutes before cutting.
