OKLAHOMA CITY (KFOR) – These fajitas are perfect if you’re looking for something a little spicy and easy to make!. In a small bowl, add your lime juice, olive oil, salt, brown sugar, oregano, chili powder, cumin, garlic powder and Daddy Hinkle’s seasoning and whisk together. Add your mixture to a sealable plastic bag, then add your skirt steak. Let marinate for at least 30 minutes or as long as one day.
