Preheat your oven to 425 degrees Fahrenheit and line a large baking sheet with parchment paper for easy cleanup.
Cut the chicken breast and cauliflower into uniform one-inch pieces to ensure even cooking throughout.
In a large bowl, toss the chicken and cauliflower with avocado oil, sea salt, and black pepper until well coated.
Spread the mixture in a single layer on the baking sheet and roast for 20 minutes until the chicken is cooked and cauliflower is tender.
While roasting, whisk together the Greek yogurt, lemon juice, dried dill, garlic powder, and onion powder to create a creamy ranch.
In a small saucepan over low heat, melt the ghee and whisk in the buffalo hot sauce until a smooth glaze forms.
Remove the tray from the oven, transfer the bites to a clean bowl, and toss thoroughly with the warm buffalo glaze.
Serve the crispy bites immediately with the chilled ranch dressing on the side for dipping.
