Preheat your oven to 425°F and line a large baking sheet with parchment paper.
In a large bowl, toss the cauliflower florets with 0.5 tbsp of melted ghee, garlic powder, sea salt, and black pepper until evenly coated.
Spread the cauliflower on the baking sheet and roast for 20 minutes until the edges are golden and tender.
While the cauliflower roasts, whisk together the remaining 0.5 tbsp of ghee and the buffalo sauce in a medium bowl.
Add the shredded chicken breast to the buffalo mixture and toss until the protein is fully saturated.
Remove the cauliflower from the oven, add the buffalo chicken to the tray, and toss everything together; roast for an additional 5-7 minutes.
In a small ramekin, stir together the Greek yogurt, crumbled blue cheese, and chopped chives to create the dipping sauce.
Serve the warm buffalo chicken and cauliflower bites immediately with the cool blue cheese dip on the side.
