Preheat your oven to 425°F and line a large baking sheet with parchment paper.
Cut the chicken breast into bite-sized cubes and break the cauliflower into small, uniform florets.
In a large mixing bowl, whisk together the melted ghee, buffalo hot sauce, garlic powder, sea salt, and black pepper.
Add the chicken and cauliflower to the bowl, tossing thoroughly until every piece is evenly coated in the buffalo mixture.
Spread the mixture onto the prepared baking sheet in a single layer to ensure even roasting and crisping.
Bake for 20 to 25 minutes, flipping the pieces halfway through, until the chicken is cooked through and the cauliflower is tender.
While the bites roast, combine the Greek yogurt, blue cheese crumbles, lemon juice, and chopped chives in a small bowl to create the dip.
Serve the warm buffalo bites immediately with the chilled blue cheese dip on the side for a satisfying, high-protein meal.
