Dice the chicken breast into small, uniform bite-sized pieces.
In a small mixing bowl, whisk together the Greek yogurt, dried dill, garlic powder, onion powder, and sea salt to create a clean ranch dressing.
Heat the ghee in a large skillet over medium-high heat until shimmering.
Add the chicken to the skillet and sauté until golden brown and cooked through, approximately 6 to 8 minutes.
Reduce the heat to low and pour the buffalo hot sauce over the chicken, stirring well to ensure every piece is thoroughly coated.
Wash and carefully pat dry the butter lettuce leaves, then arrange them on a serving plate.
Divide the buffalo chicken evenly among the lettuce leaves.
Top the chicken with finely diced celery and shredded carrots for added crunch.
Drizzle the prepared Greek yogurt ranch over the wraps and garnish with thinly sliced green onions.
