1In 12-inch skillet, cook sausage over medium-high heat, stirring occasionally, until no longer pink. Drain well. Stir in pasta sauce and water. Heat to boiling. Reduce heat to low; simmer 5 minutes.
2In medium bowl, mix ricotta cheese, chives, oregano and egg.
3In ungreased 13x9-inch (3-quart) glass baking dish or lasagna pan, spread 1 1/2 cups of the meat sauce. Top with half each of the uncooked noodles, ricotta cheese mixture and mozzarella cheese. Repeat with 1 1/2 cups meat sauce and remaining noodles, ricotta cheese mixture and mozzarella cheese. Top with remaining meat sauce. Sprinkle with Parmesan cheese. Cover; refrigerate 12 hours or overnight.
4Heat oven to 350°F. Uncover baking dish; bake 50 to 60 minutes or until noodles are tender and casserole is bubbly. Cover; let stand 15 minutes before serving.
