Preheat oven to 350 degrees.
Apply a non-stick cooking spray to a small casserole dish.
In a large bowl combine the Neufchâtel, Greek yogurt, 1/2 cup of cheddar, and Monterey Jack.
When fully mixed, add the shredded chicken, buffalo wing sauce, and the whites of the scallions with half of the green tops of the scallions. Stir well to combine.
Spoon the mixture into the prepared casserole dish. Sprinkle with remaining 1/2 cup of cheddar.
Bake for 30-35 minutes, or until golden brown.
Garnish with reserved scallions. Enjoy with celery or other sliced vegetables.
