Cook lasagna noodles in a large pot of boiling water along with 1 tsp salt and 2 tablespoon olive oil to just before al dente. Once noodles are cooked, drain and line noodles in a single layer on waxed paper or cookie sheets sprayed lightly with non-stick cooking spray to dry.
Prepare cheese mixture by whisking together ricotta cheese, egg, 1/4 tsp salt and 1/4 tsp pepper with a fork in a large mixing bowl until well combined. Stir in chopped fresh parsley, 2 cups grated mozzarella cheese, 3/4 cup Parmesan cheese and stir mixture until well combined.

Stir meat sauce, then spread about 1/3 cup evenly into a 13x9-inch baking dish.
Spread 1/4 cup of the cheese mixture evenly onto each cooked lasagna noodle in a thin layer, then spread 2 heaping tablespoons meat sauce along the top of cheese covered noodle. Roll noodles up jellyroll style and arrange seam side down in the baking dish. Cover rolled noodles with remaining meat sauce then sprinkle remaining 1/2 cup Mozzarella cheese and 1/4 cup Parmesan cheese evenly over roll-ups.
