Our original tender cuts of midwestern grain-fed fajita skirt steak aged for 21 days and hand-trimmed by our butcher
In a large bowl, combine olive oil, lime juice, garlic powder, ground cumin, chili powder, salt, and black pepper. Add the skirt steak to the bowl, ensuring it's fully coated in the marinade. Cover and refrigerate for at least 30 minutes, preferably 2-4 hours for best flavor.
While the steak is marinating, slice the bell peppers and onion into thin strips.
Preheat a grill or skillet over medium-high heat. Remove the steak from the marinade and discard the marinade. Cook the steak for about 4-5 minutes on each side for medium-rare, or until desired doneness. Remove from heat and let it rest for 5 minutes before slicing against the grain.
In the same skillet or on the grill, add the sliced bell peppers and onion. Sauté for about 5-7 minutes until they are tender and slightly charred. Season with salt and black pepper to taste.
Slice the rested steak into thin strips. Serve the steak and sautéed vegetables on warm flour tortillas. Garnish with fresh cilantro and additional lime wedges if desired.
