Preheat oven to 450ºF.
Place a large skillet over medium-high heat with 2 turns of the pan of EVOO, about 2 tablespoons. Season the chicken pieces with salt and ground black pepper, and add them to the preheated skillet. Sauté until cooked through and golden brown, 4-5 minutes.
Reduce the heat to medium and add the butter to the skillet to melt. Add the hot sauce and cook, stirring occasionally, until the sauce has thickened and coats the chicken, 2-3 minutes. (Be careful not to take a deep breath over the pan or the hot sauce fumes could burn your sinuses!)
