Preheat oven to 400°F and line a baking sheet with parchment paper.
Peel and cube the sweet potato into bite-sized pieces.
Toss sweet potato cubes with avocado oil, sea salt, and black pepper on the baking sheet.
Roast sweet potatoes for 20-25 minutes until golden brown and tender.
While potatoes roast, poach or pan-sear the chicken breast until cooked through, then shred with two forks.
In a small saucepan, melt the ghee and whisk in the buffalo hot sauce over low heat.
Combine the shredded chicken with the buffalo sauce mixture until well coated.
In a small bowl, whisk together Greek yogurt, garlic powder, and dried dill to create a clean ranch drizzle.
Assemble the bowl by layering roasted sweet potatoes, buffalo chicken, sliced celery, and shredded carrots.
Garnish with sliced green onions and a generous drizzle of the yogurt ranch.
