In a small mixing bowl, whisk together the Greek yogurt, garlic powder, dried dill, onion powder, sea salt, and black pepper to create the clean ranch dressing.
Dice the chicken breast into bite-sized pieces.
Heat a medium skillet over medium-high heat and add the ghee to coat the pan.
Add the chicken pieces to the skillet and sauté for 6-8 minutes, or until golden brown and cooked through.
Remove the skillet from the heat, pour the buffalo hot sauce over the chicken, and toss until every piece is thoroughly coated.
Warm the whole-wheat tortilla slightly in a dry pan or microwave to make it pliable.
Spread the prepared yogurt ranch across the center of the tortilla.
Layer the shredded romaine lettuce, shredded carrots, and diced celery on top of the ranch.
Add the buffalo chicken over the vegetables, fold in the sides of the tortilla, and roll it up tightly.
Slice the wrap diagonally and serve immediately.
