Heat the oven to 450º.

In a small bowl, mix together the garlic powder, oregano, cumin, coriander and thyme. Sprinkle the rub over the tenderloin with a dry hand, then rub the pork with the seasoning over both sides of the meat, pressing gently so the seasoning adheres well to the tenderloin.

Heat the oil in a large skillet over medium-high heat. Add the garlic and cook until fragrant, about 1 minute. Place the tenderloin into the skillet and cook for about 5 minutes without turning. Flip with tongs and continue cooking another 5 minutes.

Transfer the skillet to the oven and bake for about 20 minutes. Slice and serve.
