Wash and scrub the sweet potatoes thoroughly, then poke holes in them with a fork.
Place the sweet potatoes on a baking sheet and drizzle with olive oil, then sprinkle with salt and pepper.
Bake the sweet potatoes in the preheated oven for about 45-60 minutes, or until tender.
While the sweet potatoes bake, in a bowl, combine the shredded chicken and buffalo sauce. Mix well, adjusting the sauce amount to your desired spiciness.
Once the sweet potatoes are done baking, remove them from the oven and allow them to cool slightly. Cut each potato in half lengthwise and gently fluff the insides with a fork.
Spoon the buffalo chicken mixture generously into each sweet potato half.
Top each loaded sweet potato with Greek yogurt, then sprinkle a generous amount of shredded cheddar cheese on top.
Return the stuffed sweet potatoes to the oven and bake for another 10 minutes, or until the cheese is melted and bubbly.
Remove from the oven and garnish with sliced green onions.
Notes
Serve the stuffed sweet potatoes on a rustic wooden platter, and accompany with celery sticks for an extra crunch. You can also drizzle a little extra buffalo sauce on top for added flavor and visual appeal.
