Combine all salad ingredients in large bowl and set aside. Mix all dressing ingredients in a glass 1-cup measuring cup. Using a wire whisk stir until dressing is well mixed. Pour 3/4 of the dressing over the salad and stir until just moistened. NOTE: the salad will turn slightly purple. Serve 1 cup of the turkey salad on top of 1 cup of spinach leaves. Drizzle with additional dressing. Sprinkle with sliced basil leaves and toasted pecans. Refrigerate leftovers.
