For Cilantro Pesto, place cilantro, orange juice, 3 tablespoons oil, salt, and hot pepper sauce in a blender or food processor. Cover and blend or process until smooth.
Sprinkle chops with chili powder and brown sugar; rub in with your fingers. Heat 1 tablespoon oil in a 12-inch skillet over medium-high heat. Add pork. Cook for 5 minutes or until no longer pink, turning once.
