Preheat your oven to 325°F (163°C).
Pat your chicken breasts dry and season with salt and pepper. Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the chicken, skin-side down, and cook until golden brown, about 5 minutes per side. Remove from heat and transfer to a plate; set aside.
In a small bowl, whisk together the mayonnaise, white wine, chutney, curry powder, and salt.
In a large bowl, combine the diced celery, chopped scallions, raisins, and cashews. Add the cooled chicken to the mixture. Pour the dressing over the salad and mix until everything is well combined.
Refrigerate the salad for at least 2 hours before serving. Garnish with additional cashews, if desired.
