Preheat your oven to 425°F and line a large baking sheet with parchment paper to prevent sticking.
Cut the chicken breast into bite-sized pieces and break the cauliflower into small, uniform florets to ensure even cooking.
In a large mixing bowl, whisk together the melted ghee, garlic powder, onion powder, sea salt, and black pepper.
Add the chicken and cauliflower to the bowl, tossing thoroughly until every piece is evenly coated in the seasoned ghee mixture.
Spread the chicken and cauliflower in a single layer on the prepared baking sheet, leaving space between the pieces so they roast rather than steam.
Roast for 20-25 minutes, or until the chicken is cooked through and the cauliflower edges are slightly charred and crispy.
While the tray is in the oven, prepare the ranch dip by whisking the Greek yogurt, dried dill, and lemon juice in a small ramekin until smooth.
Remove the tray from the oven and immediately toss the hot chicken and cauliflower with the buffalo hot sauce in a clean bowl.
Serve the warm buffalo bites immediately with the chilled ranch dip on the side for a perfect high-protein meal.
