Use a small bowl to make the dressing. Add the rosemary, cinnamon, salt, balsamic vinegar and olive oil; whisk thoroughly to blend.
Fill a large pot 3/4 full with water and bring to a boil. Add the pasta and cook until tender (al dente), 10 to 12 minutes, or according to the package directions. Drain the pasta thoroughly and rinse under cold water.
In large bowl, combine the cooked pasta, mixed greens, pears, water chestnuts and raisins. Whisk the dressing again briefly and add to the salad. Toss to coat evenly. Divide the salad onto individual plates and top with soy nuts. Serve immediately.
