This Prawn Marie Rose Open Sandwich is just 5 Smart Points on the Weight Watchers Flex / Freestyle program. This 1960's classic makes a fantastic low point topping for an open sandwich.
With prawns being zero heroes you can mix them with a creamy marie rose sauce and pile them on top of a piece of granary bread for a tasty and filling Weight Watchers lunch.
One of the secrets for a really tasty prawn marie rose open sandwich is to use fresh prawns. The prawns are plumper, more tasty and less watery than frozen prawns.
Obviously, if you can't get your hands on any fresh prawns, then frozen prawns are more than adequate for this recipe!
Just don't bung them in the microwave to defrost they can become a watery mush!
The best way to defrost frozen prawns is mix a couple of teaspoons of salt in a bowl of cold water and plunge the frozen prawns in there for 15 - 20 minutes or until they have defrosted. Drain the prawns well before mixing them with the marie rose sauce.
For this Weight Watchers friendly marie rose sauce I used a teaspoon of Worcestershire sauce as well a dash of tobasco and some smoked paprika and cayenne pepper.
This gives the sauce a subtle 'kick' without making it so spicy that the taste of the prawns are lost.
A simpler version can be used by just mixing tomato ketchup with mayonnaise but if you really want a sauce to compliment those prawns then this sauce is the way to go!
