Put all dressing ingredients into shaker and refrigerate.
Place lettuce on 8 salad plates. Cut apples into thin wedges and place them on the lettuce. Sprinkle pecans and blue cheese evenly over each salad.
Drizzle chilled dressing over the salads.
Notes
If you prefer, you can toss the salad ingredients in a large bowl and then dish out individual salads. It "looks" prettier when you can fan out the apples on each salad.
I've use toasted cashews instead of pecans for equally great results.
WW Points were calculated using reduced fat blue cheese.
