Cook pasta according to package directions. Drain pasta; rinse with cold water and drain again.
In a large bowl combine pasta and remaining ingredients except dressing. Add dressing to pasta mixture; toss gently to coat. Cover and chill 2 to 24 hours. Makes 12 side-dish servings.
To serve the pasta Halloween-style, place it in a clean plastic cauldrin embellished with well-secured plastic spiders.
