If your chicken needs to be pounded, do so. Each piece should be roughly the same thickness throughout.
Season each side with a good amount of salt and pepper.
Set your frying pan over medium-high heat and let it heat up for about 1-2 minutes.
Add enough oil to coat the pan and then lay the chicken breast in a single layer. (You may need to do this in batches) Leave it alone (no touching) for about 3-4 minutes.
Flip and sear the other side for another 3-4 minutes or until the chicken is fully cooked. Remove from the pan onto a clean plate or cutting board and allow it to rest for 5 minutes.
Cut the chicken into cubes or strips and then place in a bowl with the buffalo sauce. Toss to coat.
Roll into wraps or tortillas with any add-ins you would like. Serve hot or chilled.
