Cook the ground beef or turkey in a large nonstick skillet over medium-high heat until browned, stirring to crumble. Drain fat off. Add sauce and bring to a boil. Reduce heat, and simmer 5 minutes.
Combine cottage cheese and Parmesan cheese in a bowl.
Spread ½ cup meat mixture in bottom of a 13x9 inch baking dish coated with cooking spray. Arrange 4 noodles over meat mixture; top with half of cottage cheese mixture, 1 cup meat mixture and ⅓ cup cheddar cheese. Repeat layers, ending with noodles. Spread remaining meat mixture over noodles.
Cover and bake for 30 to 35 minutes until noodles are tender. Uncover and sprinkle with ⅓ cup cheddar or mozzarella cheese, and bake 5 additional minutes or until cheese melts.
Let stand for 10 minutes before cutting into 9 servings. Garnish with parsley, if desired
