Preheat oven to 350 degrees F (175 degrees C). Lightly grease a 9x13 inch baking dish.
Bring a large pot of lightly salted water to a boil. Add noodles and cook for 8 to 10 minutes or until al dente; drain and rinse.
In a large bowl combine broccoli, ricotta cheese, mozzarella cheese, green onions, basil and nutmeg.
Spread about 1/2 cup of the broccoli mixture along each noodle. Roll noodles to form spirals. Place in prepared dish. Spoon spaghetti sauce on and around spirals, and top with Parmesan cheese.
