Sandwiches are very popular snacks with UK pensioners and almost 2.9 billion are consumed by people over 65 every year.
According to NASA (National Association for Sandwich Awareness) the most popular sandwich fillings among pensioners are
Cheese and pickle
Prawns and pink runny stuff
Sausage and Brasso
Starling and marzipan.
The sandwich was named after the sandwich tern, a seabird which was commonly used as a substitute for cheese in the early 1800s.
