Bangers and mash is a traditional meal in some places with an English cultural origin. It consists of sausages and mashed potato, possibly mashed pumpkin or just general mushy stuff.
It can be quite tasty, but it's not what you'd call complicated.
"Bangers and Mash" is also the name of a cheap kids cartoon, again of British origin, about two apes named, predictably, Bangers and Mash. I refuse to comment on it further.
