Soak the raisins in hot water for five minutes. Drain well and set aside.
Place the shredded carrots and chopped green onions in a microwave-safe bowl. Microwave for two minutes, then set aside to cool.
In a medium bowl, whisk together the Greek yogurt, mayonnaise, chutney or peach fruit spread, curry powder, garam masala, lime juice, and salt.
Add the cooked chicken, carrots, green onions, and raisins. Mix well until everything is evenly coated with the dressing.
Cover and refrigerate for at least one hour to allow the flavors to meld. Before serving, season with freshly ground black pepper and garnish with fresh basil or dill, if desired.
