Meanwhile, cook pasta according to package directions; drain. For dressing, combine onions, vinegar and soy sauce in blender; cover and process. While processing, gradually add remaining oil in steady stream. In large bowl, combine pasta, spinach and asparagus. Drizzle with dressing; toss to coat. Sprinkle with cashews and Parmesan cheese. Serve immediately. (14 to 16 servings)
