Creating Spicy Grilled Fish Tacos is a straightforward process that anyone can master. Just follow these simple steps:

1. Marinate the Fish: In a mixing bowl, combine olive oil, chili powder, cumin, paprika, garlic powder, salt, black pepper, cayenne pepper, and lime juice. Add the fish fillets, ensuring they are well coated. Let marinate for about 15 minutes.

2. Preheat the Grill: Heat your grill to medium-high heat. Ensure the grill grates are clean to prevent sticking.

3. Prepare the Tortillas: While the fish marinates, wrap the tortillas in foil and place them on the grill to warm for about 5 minutes.

4. Grill the Fish: Once the grill is ready, place the marinated fish fillets directly on the grill. Grill for about 3-4 minutes per side, or until the fish is cooked through and flaky.

5. Flake the Fish: Remove the fish from the grill and allow it to cool slightly. Then, flake it into bite-sized pieces using a fork.

6. Assemble the Tacos: In each warmed tortilla, add a generous amount of grilled fish, followed by shredded cabbage, cilantro, and avocado slices.

7. Add Salsa: Top your tacos with fresh salsa or pico de gallo for an added burst of flavor.

8. Add Toppings: If desired, drizzle sour cream or Greek yogurt over the top for creaminess.

9. Serve: Serve the tacos immediately while they are warm, garnished with additional lime wedges.
