Creating Grilled Steak Tacos with Corn Salsa is easy when you follow these straightforward steps:

1. Marinate the Steak (Optional): In a bowl, combine the olive oil, chili powder, cumin, garlic powder, onion powder, smoked paprika, salt, and pepper. Rub this mixture all over the flank steak. Cover and let it marinate for at least 30 minutes in the refrigerator.

2. Preheat the Grill: Heat the grill to medium-high heat. If using a grill pan, heat it on the stovetop over medium-high heat.

3. Grill the Steak: Once the grill is hot, place the marinated steak on it. Cook for about 5-6 minutes per side for medium-rare, or longer if you prefer it well done.

4. Rest the Steak: Remove the steak from the grill and let it rest for about 5-10 minutes. This allows the juices to redistribute for a juicier taco filling.

5. Prepare the Corn Salsa: While the steak is resting, combine the corn, diced tomatoes, red onion, cilantro, and lime juice in a bowl. Season with salt and pepper to taste. Mix well and set aside.

6. Warm the Tortillas: On a clean, dry skillet or the grill, warm the corn tortillas for about 30 seconds on each side until pliable.

7. Slice the Steak: Slice the rested steak against the grain into thin strips.

8. Assemble the Tacos: Place a few strips of steak on each tortilla and top with the corn salsa. Add sliced avocado if desired.

9. Serve: Squeeze fresh lime juice over the tacos and serve with lime wedges on the side for an extra burst of flavor.
