Season the chicken breast with sea salt, black pepper, and garlic powder on both sides.
Heat the olive oil in a skillet over medium-high heat and cook the chicken for about 5-7 minutes per side until golden and cooked through.
Remove the chicken from the pan, let it rest for 2 minutes, then dice into small bite-sized cubes.
In a small mixing bowl, toss the diced chicken with the buffalo sauce until every piece is well coated.
In another small bowl, whisk together the Greek yogurt, dried dill, and onion powder to create a clean, high-protein ranch dressing.
Lay the whole wheat tortilla flat on a clean surface and spread the Greek yogurt ranch across the center.
Layer the shredded romaine lettuce, diced tomatoes, sliced avocado, and buffalo chicken on top of the dressing.
Fold the left and right sides of the tortilla inward, then roll from the bottom up tightly to secure the wrap.
