Begin by preparing the Marie Rose, simply compile all ingredients into a mixing bowl and whisk well making sure there are no lumps, taste and make sure it is seasoned to your taste.
Next make the dressing for the iceberg, again, just mix all ingredients together in a separate bowl and season to taste
If you are using raw prawns* boil them in a pot of lightly salted water for 2/3 mins then transfer directly in an ice bath**.
To assemble, shred the iceberg with a sharp knife scatter a bit of fresh parley throughout and lightly toss it in a dessert spoon of the dressing (you just want a hint of dressing it should not be wet wet just glistening) , slice a quarter of an avocado and drizzle it with lemon juice
When the prawns have cooled put them in a small bowl and mix them in a tablespoon of Marie-rose sauce
In a martini glass or on a plate place a handful of iceberg , followed by the prawns and arrange the Avocado neatly to the side
Top with a sprinkle of finely chopped fresh chives and maybe a drizzle more Marie Rose & finish by placing a slice of lemon on side
Enjoy with some crusty white bread of a fresh slice of buttered Guinness bread
