Mix all marinade ingredients. Use ½ of mixture to marinate the steaks overnight, and reserve the other ½ for the slaw.
Mix cabbage, apples, and carrots. Dress with reserved marinade/dressing and refrigerate overnight for the best flavor.
Preheat oven to 425°F.
Preheat cast-iron skillet over high heat. Remove steaks from marinade and pat dry. Add ghee to pan, and once ghee has melted, sear steaks on both sides for 2 minutes per side.
Place skillet in oven and roast until thermometer inserted into thickest part of steak reads 120°F, about 6 minutes. Let rest 8 minutes before slicing thin.
Serve the steak topped with the slaw in your favorite taco shell or sticky bun. Garnish with fresh cilantro.
Enjoy!
