Brown Sugar Spiced Pork Tenderloin

I think this is one of my new favorite ways to cook pork tenderloin. I adapted this recipe from Momma Hen's Kitchen.

1 pork tenderloin
1/2 tsp black pepper
1 tsp cumin
1 tsp chili powder
1/2 tsp Cajun seasoning
 2 -3 tbs olive oil
1/2 cup brown sugar
1 tsp garlic salt

Heat oven to 350. Combine the black pepper, cumin, chili powder, cajun seasoning, brown sugar and garlic salt.  Heat olive oil in a pan over medium heat.  Rub the pork tenderloin with the mixture. Sear the pork tenderloin on each side for 3 to 4 minutes.  Place in the oven and cook for 25 more minutes.  Let rest for 5 minutes before slicing.
