Preheat oven to 450°F (230°C).

In a small bowl, combine garlic powder, oregano, cumin, coriander, thyme, and salt. Mix well with a fork to form a seasoning rub.

Sprinkle the spice rub over the pork tenderloin and rub it in evenly on all sides, pressing gently so the seasoning sticks.

Heat olive oil in a large skillet over medium high heat. Add the minced garlic and sauté for about 1 minute until fragrant.

Place the tenderloin in the skillet and sear for about 10 minutes, turning with tongs to brown all sides.

Transfer the pork to a roasting pan and bake in the preheated oven for 20 minutes, or until the internal temperature reaches 145°F.

Let rest for 5 minutes before slicing. Serve warm.
