Dice the chicken breast into small, bite-sized pieces and season with sea salt and black pepper.
Heat avocado oil in a skillet over medium-high heat and sauté the chicken until golden brown and cooked through.
In a small saucepan or microwave-safe bowl, melt the ghee and whisk in the buffalo hot sauce until fully combined.
Pour the buffalo sauce mixture over the cooked chicken in the skillet and toss until every piece is well coated.
In a small mixing bowl, whisk together the Greek yogurt, lemon juice, garlic powder, onion powder, and dried dill to create the ranch dressing.
Carefully wash and dry the butter lettuce leaves, arranging them on a serving plate.
Divide the buffalo chicken evenly among the lettuce leaves and top with diced celery and shredded carrots.
Drizzle the homemade ranch dressing over the wraps and garnish with sliced green onions before serving.
