Dice the chicken breast into small, bite-sized pieces and season evenly with sea salt and black pepper.
Heat the avocado oil in a skillet over medium-high heat and sauté the chicken until golden brown and cooked through, approximately 6 to 8 minutes.
Remove the skillet from heat and toss the chicken in the buffalo sauce until every piece is thoroughly coated.
In a small mixing bowl, whisk together the Greek yogurt, dried dill, garlic powder, and onion powder to create a clean, high-protein ranch dressing.
Warm the whole wheat tortilla in a dry pan over medium heat for 30 seconds per side until soft and pliable.
Spread the Greek yogurt ranch across the center of the tortilla, then layer with shredded romaine lettuce, diced tomatoes, and sliced avocado.
Top the vegetables with the buffalo chicken, fold in the sides of the tortilla, and roll it up tightly into a wrap.
