I shudder to think of the replys I'll get with this title but...

I was at the grocery store the other day and I saw that the butcher shop was selling Bangers. I know that they are sausages. Are they spicy ? Mild ? Pork ? Beef ? All of the above ? Mystery meat ? Are they just for breakfast ? Or anytime you need a little sausage in your life ?

And bangers and mash are sausages with mashed potatoes - correct ? How else are they served ?

Thanks.
