Wash the sweet potatoes thoroughly and pierce them several times with a fork.
Place the sweet potatoes on a baking sheet and bake for 45-55 minutes, or until they are tender and cooked through.
While the sweet potatoes are baking, in a medium bowl, combine the shredded chicken, buffalo sauce, cream cheese, and half of the cheddar cheese. Mix well until smooth and creamy.
Once the sweet potatoes are done baking, remove them from the oven and allow them to cool slightly.
Carefully slice each sweet potato down the middle and gently fluff the flesh with a fork.
Spoon the buffalo chicken mixture generously into each sweet potato half.
Sprinkle the remaining cheddar cheese on top of the stuffed sweet potatoes.
Return the stuffed sweet potatoes back to the oven and bake for an additional 10 minutes, or until the cheese is melted and bubbly.
Remove them from the oven, and drizzle Greek yogurt on top of each stuffed potato.
Garnish with sliced green onions and season with salt and pepper to taste.
Notes
Serve on a rustic wooden platter with extra green onions and buffalo sauce for dipping.
