Prepare Homemade Manicotti Wraps (if using) or cook purchased manicotti shells according to package directions. Set aside. For filling: In a large bowl, combine ricotta cheese, 1 cup of the mozzarella cheese, the eggs, Romano cheese, the 1/4 cup parsley, the salt, and pepper.

Preheat oven to 350 degrees F. Mix together tomato sauce and Italian seasoning in a bowl. Spread 1 cup of the tomato sauce in the bottom of a 3-quart rectangular baking dish. If using Homemade Manicotti Wraps, spoon about 3 tablespoons of the filling down the center of each wrap. Wrap sides around filling. Arrange wraps, seam sides down, in prepared baking dish, stacking as needed to fit all in the dish. (If using purchased manicotti shells, spoon about 3 tablespoons of the filling into each cooked shell. Arrange in prepared baking dish.) Spoon remaining tomato-herb sauce evenly over filled wraps or shells in baking dish.

Bake for 35 to 40 minutes or until heated through. Sprinkle with the remaining 1 cup mozzarella cheese. Bake for 5 minutes more or until cheese is melted. Let stand on a wire rack for 10 minutes before serving. If desired, sprinkle with additional parsley. If using Homemade Manicotti Wraps, cut into portions to serve. (Or serve two purchased manicotti per serving.)

Homemade Manicotti Wraps: In a medium bowl, stir together flour and salt. In another bowl, combine water, milk, and egg. Add the water mixture to the flour mixture; whisk until smooth. Lightly coat a 5- to 6-inch nonstick skillet with nonstick cooking spray. Preheat over medium heat. Remove from heat and add about 1-1/2 tablespoons of the batter to the hot skillet. Quickly tilt skillet to make an even layer of batter on the bottom of the skillet. Return to heat. Cook about 1 minute or just until top looks dry. Invert wrap onto a paper towel, using a small spatula to help release edge from skillet if necessary. Set wrap aside. Repeat with remaining batter to make about 20 wraps. If desired, layer the wraps between waxed paper in an airtight container; cover and chill for up to 24 hours before using.
