Put all dressing ingredients in a medium bowl and whisk together. Cover and refrigerate.
PREPARE THE CHICKEN SALAD:
Remove the skin from the roasted chicken; discard. Remove the meat from the bones; discard the bones. Coarsely chop the chicken (you should have about 3 cups). In a very large bowl combine the chicken, fruit, jicama, and green onion. Spoon about half the dressing over the chicken salad; toss to coat well.
Line 6 individual serving plates with Bibb lettuce. Arrange some of the chicken mixture on each plate. Drizzle with some of the remaining dressing.
