Season the chicken breast with sea salt and black pepper.
Heat the avocado oil in a medium skillet over medium-high heat.
Add the chicken to the skillet and cook for 5-7 minutes per side until golden brown and cooked through.
While the chicken cooks, whisk together the Greek yogurt, dried dill, and garlic powder in a small bowl to create the ranch dressing.
In a separate small bowl, combine the hot sauce and ghee, whisking until smooth and emulsified.
Slice the cooked chicken into strips and toss them in the buffalo ghee mixture until thoroughly coated.
Warm the whole wheat tortilla in a dry pan for 30 seconds until pliable.
Spread the Greek yogurt ranch onto the center of the tortilla, then layer with romaine lettuce and diced tomatoes.
Place the buffalo chicken on top of the vegetables, fold in the sides, and roll the tortilla tightly into a wrap.
