Slice the chicken breast into small, bite-sized strips for even cooking.
Season the chicken strips thoroughly with sea salt and garlic powder.
Heat the avocado oil in a large skillet over medium-high heat until shimmering.
Add the chicken to the skillet and sauté until golden brown and cooked through, about 6-8 minutes.
Reduce heat to low and pour the buffalo sauce over the chicken, tossing until every piece is coated.
In a small bowl, whisk together the Greek yogurt, dried dill, onion powder, and lemon juice to create a tangy ranch dressing.
Lay the whole wheat tortilla flat and layer the crisp romaine lettuce and sliced cherry tomatoes in the center.
Top the vegetables with the buffalo chicken and drizzle with the prepared Greek yogurt ranch.
Fold the sides of the tortilla inward and roll tightly to form a wrap.
Place the wrap back in the skillet for 1 minute per side to achieve a toasted, crunchy exterior.
