2 whole pork tenderloins (about 1 1/2 pounds total)
5 teaspoons chili powder
1 1/2 teaspoons oregano
3/4 teaspoon ground cumin
2 garlic cloves, crushed
Mix together chili powder, oregano, cumin and garlic and rub over surfaces of tenderloins. Cover and refrigerate for 2 to 24 hours.
Grill over medium-hot coals, turning occasionally, for 15 to 20 minutes, until inserted thermometer reads 160 degrees F. Pork is done when there is still a hint of pink in the center.
Slice to serve.
