Preheat oven to 425°F and line a large baking sheet with parchment paper.
Cut the chicken breast and cauliflower into uniform, bite-sized pieces for even cooking.
In a large mixing bowl, whisk together the melted ghee, buffalo hot sauce, garlic powder, onion powder, sea salt, and black pepper.
Add the chicken and cauliflower to the bowl, tossing well until every piece is thoroughly coated in the spicy glaze.
Spread the mixture in a single layer on the prepared baking sheet, ensuring pieces aren't crowded.
Roast for 20 to 25 minutes, or until the chicken is cooked through and the cauliflower is tender with charred edges.
While the bites roast, whisk together the Greek yogurt, blue cheese crumbles, lemon juice, and dried dill in a small bowl.
Serve the hot buffalo bites immediately with the chilled blue cheese dip on the side for a protein-packed meal.
