Cut the chicken breast into small, bite-sized pieces for even cooking.
In a small bowl, whisk together the Greek yogurt, lemon juice, garlic powder, onion powder, dried dill, sea salt, and black pepper to create the ranch dressing.
Finely dice the celery stalk and grate the carrot to provide a refreshing crunch.
Heat the ghee in a large skillet over medium-high heat until shimmering.
Add the chicken to the skillet and sauté for 6 to 8 minutes until golden brown and fully cooked.
Reduce the heat to low and pour the buffalo sauce over the chicken, tossing well to ensure every piece is coated.
Arrange the butter lettuce leaves on a plate and divide the buffalo chicken evenly among them.
Top the wraps with diced celery, shredded carrots, and sliced avocado, then finish with a generous drizzle of the homemade ranch.
