Whisk espresso powder, spices and herbs together in a medium bowl. Completely coat all sides and edges of pork tenderloin with rub. Place coated tenderloins on greased/sprayed 10x15-inch rimmed baking sheet. Roast until pork reaches 145 degrees on instant read thermometer, about 15 to 20 minutes. Let rest at least 3 minutes before slicing.
