Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper.
Cut the chicken breast into bite-sized pieces and chop the cauliflower into small, uniform florets.
In a large mixing bowl, whisk together the melted ghee and buffalo sauce until well combined.
Add the chicken and cauliflower to the bowl, tossing thoroughly until every piece is evenly coated in the buffalo mixture.
Spread the chicken and cauliflower onto the prepared baking sheet in a single layer, ensuring they are not overcrowded.
Sprinkle the garlic powder, onion powder, sea salt, and black pepper over the tray.
Roast for 20 to 25 minutes, flipping the pieces halfway through, until the chicken is cooked through and the cauliflower is tender with crispy edges.
While the bites roast, whisk together the Greek yogurt, dried dill, and lemon juice in a small bowl to create the dipping sauce.
Remove the tray from the oven and serve the buffalo bites immediately with the creamy herb dip on the side.
