Wash the sweet potatoes thoroughly and poke holes in them with a fork. Place them on a baking sheet and drizzle with a little olive oil, then sprinkle with salt.
Bake in the preheated oven for 45-60 minutes, or until tender when pierced with a fork.
While the sweet potatoes are baking, in a mixing bowl, combine the shredded chicken and buffalo sauce. Adjust the amount of sauce according to your desired heat level.
Once the sweet potatoes are done, let them cool slightly before cutting them in half lengthwise.
Scoop out a bit of the sweet potato flesh (keep the skins intact), and mix it with the buffalo chicken mixture, Greek yogurt, and ranch dressing. Add salt and pepper to taste.
Stuff the sweet potato skins with the buffalo chicken mix and top with shredded cheddar cheese.
Return the stuffed sweet potatoes to the oven and bake for an additional 10-15 minutes until the cheese is bubbly and melted.
Remove from the oven and garnish with chopped green onions before serving.
Notes
Serve the stuffed sweet potatoes on a wooden platter and drizzle extra ranch dressing on top. Optionally, garnish with additional green onions for a pop of color.
