4 - Whiting Fillets
haddock or hake fillets can also be used. Skinned, deboned and butterflied
Method
Cut the fish fillets into fingers. Put the taco seasoning in a shallow bowl, add the fish fingers and toss to coat, shaking off any excess.
Heat a drizzle of rapeseed oil in a large frying pan set over a medium heat, then add the fish. You should hear it sizzle. Cook for 2 minutes on each side.
Meanwhile, make a cocktail sauce by mixing the mayo and ketchup together and toast the buns.
When the fish is cooked through, build your roll using the cocktail sauce as a base. Add some avocado slices and lettuce and top with the fish fingers.
