Mix together the paprika, cayenne, onion powder, garlic powder, basil, oregano, thyme, sea salt and ground black pepper.
Pat your fish dry then coat both sides of the fish with the spice rub and press it into the flesh.
Add the cabbage, onion, cilantro, lime juice and avocado oil to a medium sized bowl then season well with sea salt and pepper. Set aside.
Heat a large non-stick frying pan to medium high heat then add a touch of oil. When the pan is hot place the fish in it and cook on the first side for 2-3 minutes. Flip the fish over carefully and cook the second side for the same.
Remove the fish from the pan for it to cool then flake into chunks.
Serve together on tortillas.
when using the full teaspoon of cayenne the fish is quite spicy. Stick to half a teaspoon or less is you don't like things on the spicier side.
