Heat a large skillet or cast iron over medium-high heat. After pan is pre-heated, add the EVOO. Just before it starts smoking, add the tenderloins. Cook a few minutes, undisturbed on each side, rotating so each side is browned. Place in the oven, top rack, until pork temps out at 145F (approx. 15 mins.) Remove, place on a cutting board and tent with foil to let rest and keep warm.
