Creating Delicious Skirt Steak Tacos is straightforward when you follow these simple steps:

1. Marinate the Steak: In a bowl, combine olive oil, lime juice, chili powder, cumin, garlic powder, salt, and pepper. Coat the skirt steak in the marinade and let it rest for at least 15 minutes.
2. Preheat the Grill: Heat your grill or a grill pan over medium-high heat until hot.
3. Grill the Steak: Place the marinated skirt steak on the grill. Grill for 3-4 minutes per side for medium-rare, or until it reaches your desired doneness.
4. Rest the Steak: Once cooked, remove the steak from the grill, and let it rest for about 5 minutes.
5. Slice the Steak: Thinly slice the steak against the grain to ensure tenderness.
6. Prepare the Tortillas: While the steak is resting, warm the tortillas on the grill for about 30 seconds on each side or until soft.
7. Assemble the Tacos: Place a few slices of steak on each tortilla. Top with diced onions, cilantro, and any additional toppings you prefer, such as avocado or salsa.
8. Serve with Lime: Squeeze fresh lime juice over the assembled tacos for an extra burst of flavor.
