1. Arrange equal amounts of the salad greens on each of 4 dinner plates.
2. Spoon equal amounts of the dressing evenly over all.
3. Top with the chicken, onions and pears. Sprinkle evenly with the blue cheese and black pepper, if desired.
For additional flavor and texture: Add 1/2 cup dried cranberries or unsweetened cherries on top with 2 ounces thinly sliced red onion (about 1/2 cup).
For a lighter version: Use reduced fat blue cheese and fat-free dressing.
