In a small bowl add the prawns, sprinkle over the cajun seasoning and grate over the zest of 1 lime. Stir and then pop to one side to marinade whilst you prep the accompaniments (give them at least 5 minutes to sit).
Next put the ingredients for the avocado cream in a food processor, whizz til smooth and pop into a bowl.
Next chop the vegetables for the salsa (red onion, spring onion, tomatoes and coriander). Pop the chopped vegetables into a large bowl with the black beans and sweetcorn. Add the lime juice and salt. Stir and pop the bowl to one side.
Now you are ready to cook. Take a large frying pan, spray with 1kal and then add the prawns in a single layer. Season with salt and pepper and cook on 1 side for 2 minutes. Then spray again with 1kal, flip and fry for another 2 minutes on the other side until cooked through.
Take the prawns off the heat and pop into a bowl.
Get everything ready on the table or bench, I like to set out a little production line so we can make our own tacos. Pop the lettuce in one bowl and the pickled red cabbage in another.
Warm the tortillas (in the oven or microwave).
Assemble – I like to add a little avocado cream to the base, top with lettuce and red cabbage, then the salsa, then the prawns and then a little more avocado cream.
Enjoy!
