Spinach and Chicken Manicotti

1 8oz. pkg manicotti
2 chicken breasts cooked and finely shredded
2 cups whole milk ricotta cheese (1 container)
2 cups shredded mozzarella cheese
1/4 cup grated Parmesan cheese
1/2 cup frozen spinach, thawed and chopped
1/2 tsp salt
1/4 tsp pepper
1 32oz jar spaghetti sauce

Cook pasta. Drain and cool on waxed paper to prevent noodles from sticking together. In bowl, combine cheeses, spinach, chicken, salt and pepper. Fill manicotti with cheese mixture. (An easy method is to put mixture in a ziplock bag, cut corner, then pipe the filling into each noodle.) In a 9x13 pan, spread a thin layer of spaghetti sauce on the bottom, then arrange manicotti in a single layer. Cover the manicotti with the remaining sauce. Sprinkle on more cheese, if desired. Cover dish with aluminum foil and bake at 350 degrees for 40 minutes. Remove foil and bake for 15 minutes longer.
