Preheat your oven to 425°F and line a large baking sheet with parchment paper for easy cleanup.
Toss the cauliflower florets with olive oil and half of the sea salt and black pepper directly on the baking sheet.
Roast the cauliflower for 20 to 25 minutes, flipping halfway through, until the edges are golden and crispy.
While the cauliflower is roasting, season the chicken breast with half of the garlic powder, onion powder, and the remaining salt and pepper.
Grill the chicken over medium-high heat for 6 to 7 minutes per side until the internal temperature reaches 165°F.
In a small bowl, whisk together the Greek yogurt, dried dill, lemon juice, and the remaining garlic and onion powders to create the ranch dip.
In a large mixing bowl, combine the buffalo sauce and melted ghee until smooth.
Slice the grilled chicken into bite-sized cubes and add them to the large bowl along with the roasted cauliflower.
Toss everything until well-coated in the buffalo glaze and serve immediately with the chilled ranch dip on the side.
