Bring a pan of salted water to a boil; cook the lasagna leaves 8 to 10 minutes, so that they are al dente. Drain.
In the blender, combine tofu, nutritional yeast, salt, pepper, nutmeg, milk, parsley.
Spread lasagna at a bottom of a rectangular dish. Alternate layers of tofu mixture, marinara sauce and lasagna leaves until no more. Finish by sprinkling mozzarella on top.
