1.Cook pasta in a saucepan of boiling salted water for 10 minutes or until tender. Drain. Rinse under cold running water; drain well.
2.Combine oil, vinegar and mustard in a bowl. Add pasta, chicken, beets, tomato, spinach and hazelnuts; toss to combine. Season. Serve.
Omit hazelnuts. You can use any short pasta. Assemble salad just before serving. Try sun-dried tomatoes instead of regular tomatoes. Toss bought antipasto vegetables through the salad. Try sliced salami in this salad. Instead of baby spinach, mixed salad leaves are fine.
