Boil the chicken until fully cooked, about 25-40 minutes.
Toast the slivered almonds in a dry saute pan for 5-8 minutes until slightly browned and fragrant.
Pull chicken from the bone, discarding the fat and bones. Tear into bite sized pieces.
In a large bowl, combine the chicken, greek yogurt, cilantro, toasted almonds, celery, scallions, curry powder, lemon juice, salt, pepper, garlic powder and onion powder. Stir well and set aside in the fridge to cool and meld together for 15-20 minutes.
