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.
In a large mixing bowl, combine the chicken, cauliflower, olive oil, garlic powder, onion powder, sea salt, and black pepper, tossing until everything is well-coated.
Spread the mixture in a single layer on the prepared baking sheet and roast for 20 minutes, or until the chicken is cooked through and the cauliflower is tender.
While the base roasts, prepare the dip by whisking together the Greek yogurt, blue cheese crumbles, lemon juice, and hemp seeds in a small bowl.
Remove the baking sheet from the oven and drizzle the buffalo sauce over the roasted chicken and cauliflower, tossing gently with tongs to glaze.
Serve the warm buffalo bites immediately alongside the chilled, creamy blue cheese dip.
