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 cubes and break the cauliflower into small, uniform florets to ensure even cooking.
In a large mixing bowl, toss the chicken and cauliflower with the olive oil, sea salt, black pepper, and half of the garlic and onion powders.
Spread the mixture in a single layer on the prepared baking sheet and roast for 20 to 25 minutes until the chicken is fully cooked and the cauliflower is tender.
While the tray is in the oven, whisk together the Greek yogurt, dried dill, lemon juice, and the remaining garlic and onion powders in a small bowl to create the ranch dip.
In a small saucepan or microwave-safe dish, melt the ghee and whisk it into the buffalo sauce until smooth.
Transfer the roasted chicken and cauliflower to a clean bowl, pour the buffalo glaze over them, and toss gently to coat every piece.
Serve the warm buffalo bites immediately with the chilled ranch dip on the side for a perfect balance of heat and creaminess.
