Preheat the oven to 350 degrees F.
Place the chicken breasts on a sheet pan and rub the skin with olive oil.
Sprinkle liberally with salt and pepper. Roast for 35 to 40 minutes, until the
chicken is just cooked. Set aside until cool enough to handle. Remove the meat
from the bones, discard the skin, and dice the chicken into large bite-size
pieces.
For the dressing, combine the mayonnaise, wine, mango, lime juice, honey,
ginger, curry powder, and 1 1/2 teaspoons salt in the bowl of a food processor
fitted with the steel blade. Process until smooth.
Combine the chicken with enough dressing to moisten well. Add the celery,
scallions, sliced onion, and raisins, and mix well. S & P to taste.
Refrigerate for a few hours to allow the flavors to blend. Add the cashews and
serve at room temperature.
