Place asparagus in a 13-by-9-by-2-inch baking dish. Drizzle with 2 tablespoons oil; sprinkle with salt. Bake, uncovered, at 400 degrees for 20-25 minutes or until crisp tender, stirring every 10 minutes. Meanwhile, cook pasta according to package directions; drain.
For dressing, combine the onions, vinegar and soy sauce in a blender; cover and process. While processing, gradually add the remaining oil in a steady steam.
In a large salad bowl, combine pasta, spinach and asparagus. Drizzle with dressing; toss to coat. Sprinkle with cashews and Parmesan cheese. Serve immediately.
