Meanwhile, mix ricotta, zucchini, spinach, egg, salt and pepper in a large bowl.
Preheat oven to 350. Add 1 cup of tomato sauce to the bottom of a casserole dish.
Lay down a lasagna noodle on a flat surface and spread ricotta mixture evenly on top. Sprinkle lightly with mozzarella and roll it up. Place in your casserole dish with the seam side down. Repeat with the other lasagna noodles.
Spoon additional sauce on top of each roll and sprinkle with the remaining mozzarella cheese.
Bake in the oven for 25 minutes. Remove from oven and sprinkle with fresh basil.
