Cook lasagna noodles in a large pot of water until al dente, according to package directions.
While the noodles cook, lightly beat an egg in a medium size bowl. Add ricotta cheese, pepper, salt, and garlic salt and mix well.
Then add in 1 cup grated Parmesan, 2 cups of shredded mozzarella, and 2 tablespoons of chopped parsley. Stir until mixed and set aside.
Lay out cooked lasagna noodles on 2 baking sheets. (Be sure to not let the noddles cool too much because they'll start to stick) I rinse the noodles with cold water.
Cook up your ground beef and sauce. Stir until warm. Then set aside.
Preheat Oven to 350 degrees Fahrenheit
Spread enough pasta sauce in the bottom of a 9x13 glass pan to lightly coat. Set aside.
Evenly spread a thin layer of cheese mixture down the center of each noodle.
Spread a spoonful of the meat sauce down each noodle, on top of the cheese mixture.
Roll each noodle up, and place seam side down in prepared baking dish.
Top the roll ups with remaining sauce.
Sprinkle with remaining 2 cups of mozzarella cheese, ⅓ cup grated Parmesan, and 1 tablespoon chopped parsley.
Loosely tent with aluminum foil and bake for 35 minutes.
