In a large mixing bowl, combine the shredded chicken, softened cream cheese, hot wing sauce, Greek yogurt, shredded cheddar cheese, and ranch seasoning mix until well blended.
Transfer the mixture to an 8x8 or 9x9 inch baking dish, spreading it out evenly.
If you like, sprinkle additional shredded cheese on top for a cheesier crust.
Bake in the preheated oven for 20-25 minutes, or until the dip is hot and bubbly.
Garnish with chopped green onions and serve with a side of carrots, celery, and tortilla chips.
