Mix the cajun and cayenne on a plate and coat the fish all over
Heat the vegetable oil in a frying pan and fry the coated fish over medium heat until golden, then reduce heat and cook through (about 10 minutes), cooking in batches if needed
Combine sour cream, lemon and chopped garlic to make the dressing
Soften the tortillas in the microwave for 5–10 seconds
Fill tortillas with avocado, lettuce and spring onion, add a spoonful of salsa, top with large flakes of cooked fish and drizzle with the dressing
