Season the chicken breast evenly with sea salt, black pepper, and garlic powder.
Heat avocado oil in a medium skillet over medium-high heat and sear the chicken for 5-7 minutes per side until fully cooked.
Remove chicken from heat, let it rest for a few minutes, then dice it into bite-sized pieces.
Place the diced chicken in a small bowl and toss thoroughly with the buffalo sauce.
In a separate small ramekin, whisk together the Greek yogurt and dried dill to create a clean ranch spread.
Lay the tortilla flat and spread the yogurt ranch across the center, leaving room at the edges.
Layer the shredded romaine, carrots, celery, and avocado slices onto the tortilla.
Top with the buffalo chicken, fold in the sides, and roll tightly to secure the wrap.
