In a medium bowl, whisk together mayonnaise, plain yogurt, lemon juice, honey, curry powder, ground ginger, minced garlic, salt, and pepper until smooth and well combined.
In a large bowl, combine the chopped cooked chicken, diced red onion, finely diced celery, diced green onions, cashews, raisins, and shredded carrots.
Pour the dressing over the salad mixture and toss gently until everything is evenly coated.
Garnish with additional green onions if desired, then serve immediately or refrigerate until ready to serve.
