People who have ever had afternoon tea or 'ha mg cha' will know that
the club sandwich, known as 'gung si sah man ji' in chinese, is a
regular on restaurant menus. A club sandwich basically consists of two
layers of fillings sandwiched between three slices of bread, normally
toasted. Bacon, lettuce and tomato are normally the main ingredients in
this but you can put whatever you like in it.
