Preheat your oven to 425°F (220°C) and line a large baking sheet with parchment paper for easy cleanup.
Cut the chicken breast into bite-sized pieces and break the cauliflower into small, uniform florets.
In a medium bowl, whisk the egg white until it becomes light and frothy.
In a separate shallow dish, whisk together the almond flour, garlic powder, onion powder, sea salt, and black pepper.
Dip each piece of chicken and cauliflower into the egg white, then dredge in the almond flour mixture until evenly coated.
Arrange the coated pieces on the prepared baking sheet in a single layer, ensuring they are not touching.
Roast for 20 to 25 minutes, flipping halfway through, until the coating is golden brown and the chicken is cooked through.
While roasting, melt the ghee and whisk it together with the buffalo hot sauce in a large mixing bowl.
In a small ramekin, stir together the Greek yogurt, dried dill, and lemon juice to create a clean, high-protein ranch dip.
Gently toss the roasted chicken and cauliflower in the buffalo sauce mixture until fully glazed.
Serve the crispy bites immediately with the ranch dip and fresh avocado slices on the side.
