Preheat your oven to 425°F and line a large baking sheet with parchment paper for easy cleanup.
Cut the chicken breast into bite-sized chunks and break the cauliflower into small, uniform florets.
In a large mixing bowl, combine the chicken and cauliflower with the almond flour, garlic powder, smoked paprika, sea salt, and black pepper, tossing until every piece is lightly coated.
Spread the mixture in a single layer on the prepared baking sheet and roast for 20 minutes, flipping halfway through, until the chicken is cooked through and the cauliflower is tender.
While the tray roasts, whisk together the buffalo sauce and melted ghee in a small bowl until emulsified.
Prepare the ranch dip by stirring together the Greek yogurt, dried dill, onion powder, and lemon juice in a separate small ramekin.
Remove the tray from the oven and immediately toss the hot chicken and cauliflower in the buffalo-ghee mixture until fully glazed.
Serve the crispy bites on a platter with the cool ranch dipping sauce on the side for a protein-packed, clean-eating meal.
