In a large mixing bowl, add the chopped chicken, halved grapes, diced green onions, and sliced almonds. Stir gently to combine.

In a separate bowl, whisk together the mayonnaise, lemon juice, curry powder, salt, garlic powder, onion powder, and black pepper until smooth.

Pour the dressing over the chicken mixture and gently fold until everything is coated evenly.

Serve immediately or transfer to an airtight container and refrigerate for serving later.
