Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Cut the chicken breast and cauliflower into uniform, bite-sized pieces to ensure even cooking.
In a large mixing bowl, toss the chicken and cauliflower with the extra virgin olive oil, sea salt, and black pepper until every piece is well coated.
Spread the mixture in a single layer on the prepared baking sheet, ensuring they are not overcrowded.
Roast for 20-22 minutes, or until the chicken is cooked through and the cauliflower is tender with golden, caramelized edges.
While the bites are roasting, whisk together the Greek yogurt, dried dill, garlic powder, onion powder, and lemon juice in a small bowl to create the ranch dip.
Once the tray is out of the oven, transfer the roasted chicken and cauliflower to a clean bowl and toss with the buffalo sauce until fully glazed.
Serve the warm buffalo bites immediately with the chilled ranch dip on the side.
