Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Cut the chicken breast into bite-sized pieces and break the cauliflower into small, uniform florets.
In a large bowl, whisk together the melted ghee, 0.25 tsp garlic powder, 0.25 tsp 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 spiced ghee.
Spread the mixture in a single layer on the baking sheet and roast for 20-25 minutes until the chicken is cooked through and the cauliflower is tender with charred edges.
While roasting, prepare the ranch dip by whisking together the Greek yogurt, lemon juice, dried dill, and the remaining garlic and onion powder in a small bowl.
Once the roasting is complete, transfer the chicken and cauliflower back to the large bowl and toss with the buffalo sauce until well coated.
Serve the warm buffalo bites immediately alongside the chilled ranch dip for a high-protein, clean-eating meal.
