Step 1

Mix the remoulade ingredients together and season well.

Step 2

Mix the flour with half the Cajun spice mix and put on a plate. Mix the breadcrumbs with the rest of the spice mix and put on another plate.

Step 3

Dip the prawns first in the flour, then the egg, then the breadcrumbs. Heat 3cm oil in a large, wide frying pan. Cook the prawns for a minute on each side, until golden. Drain on kitchen paper.

Step 4

Split the bread ¾ of the way through. Spread all over with remoulade and add some lettuce. Pile on the prawns and eat.
