Easy Pork Tenderloin

2 t oregano
2 t cumin
1 t chili powder
1 t paprika (smoked if you have it)
1 t salt
1/s t pepper
1 t rosemary
1 tsp thyme
1 tsp onion powder

Preheat oven to 400 degrees. Combine all the spices.  Pat average pork tenderloin dry.  Using the spice mixture rub on all sides of pork tenderloin.  Preheat cast iron skillet.  Heat 2 tsp olive oil.  Brown all sides of tenderloin.  Once meat is browned, pop in the preheated oven for about 30 minutes.  Roast until about 145 internal temperature has been reached.  Allow to rest for 10 minutes before slicing. This will allow the juices to return to the meat and not spill out onto the plate rendering the pork tenderloin dry.
