Pat the chicken breast dry with a paper towel and season both sides evenly with sea salt and black pepper.
Heat the olive oil in a medium skillet over medium-high heat and sear the chicken for 5-6 minutes per side until the internal temperature reaches 165 degrees Fahrenheit.
While the chicken cooks, whisk together the Greek yogurt, dried dill, and garlic powder in a small bowl to create a clean, high-protein ranch dressing.
Remove the chicken from the pan, let it rest for 2 minutes, then slice it into thin strips.
In a small mixing bowl, toss the sliced chicken with the buffalo sauce until every piece is thoroughly coated.
Lay the whole wheat tortilla flat on a clean surface and layer the romaine lettuce, shredded carrots, and sliced avocado in the center.
Place the buffalo chicken strips over the vegetables and drizzle the prepared Greek yogurt ranch dressing on top.
Fold the left and right sides of the tortilla inward, then roll from the bottom up tightly to secure the wrap before slicing diagonally.
