In a large skillet, brown the sausage over medium heat. Drain any accumulated fat and discard. Add the jarred sauce, and stir to combine.
PREPARE THE ROLL UPS:
Preheat the oven to 375℉. Spray a 9x13-inch dish with nonstick spray.
Cook the lasagna noodles according to the package instructions until tender. Drain and rinse. Lay the cooked noodles out on a cutting board.
In a medium bowl, combine the ricotta cheese, Parmesan cheese, eggs, parsley, salt and pepper.
Add ¾ cup of the meat sauce to the bottom of the prepared pan.
Spread onto each noodle a little more than ¼ cup of the ricotta mixture. Sprinkle a thin layer of the mozzarella cheese on next. Roll up each noodle and place seam-side down in the pan- lay them out in rows. Spread the rest of the sauce evenly over the noodles in the pan). Top with the remaining mozzarella cheese.
Place the pan on the lower rack of your oven and bake for 25 to 30 minutes. Let sit for 5 to 10 minutes prior to serving.
