Preheat your oven to 425°F and line a large rimmed baking sheet with parchment paper.
In a large mixing bowl, whisk together the melted ghee, buffalo hot sauce, and almond flour until a smooth glaze forms.
Add the cauliflower florets and the chicken breast, which should be cut into bite-sized cubes, to the bowl.
Toss the mixture thoroughly until every piece of chicken and cauliflower is evenly coated in the buffalo sauce.
Spread the bites in a single layer on the prepared baking sheet, ensuring they are spread out to allow for even roasting.
Roast for 20 to 25 minutes, flipping the pieces halfway through, until the chicken is cooked through and the cauliflower is tender with slightly charred edges.
While the bites are roasting, prepare the ranch dip by whisking together the Greek yogurt, lemon juice, dried dill, garlic powder, sea salt, and black pepper in a small bowl.
Remove the tray from the oven and serve the hot buffalo bites immediately alongside the chilled ranch dip.
