Simple Lasagna

1 container (15 oz) part skim ricotta cheese. (I use a 16 oz. container of low fat cottage cheese)
2-½ cups mozzarella cheese, divided
½ cup grated Parmesan cheese, divided
¼ cup chopped parsley (I use a couple T of dried parsley)
1 egg lightly beaten
1 jar of spaghetti sauce
1 lb ground beef(or chicken), cooked
1 cup water
12 lasagna noodles
Preheat oven to 350. Mix ricotta cheese, 1 ¼ cup of mozzarella, ¼ Parmesan, parsley and egg until well blended. Set aside. Pour spaghetti sauce into meat in skillet. Pour water into empty sauce jar and shake well. Pour into skillet, stir until well mixed. Place 1 cup of meat sauce on bottom of the 9x13 dish(prevents noodles from sticking to the pan) Layer 3 lasagna noodles, 1/3 of ricotta cheese mixture and 1 c of meat sauce. Repeat layers 2 more times. Tops with remaining 3 noodles and sauce. Sprinkle with remaining mozzarella and Parmesan. Cover tightly with greased aluminum foil. Bake 45 min or until cooked through. Remove foil and bake an additional 15 min. Let stand 15 min before cutting.
