Sainsbury's liver sausage was good and even better when fried for breakfast. You can still get it in some stores.
Sainsbury's Pork Breakfast Sausage is still one of my favourites. I can still remember going into Sainsburys, before it was a supermarket, with my mum and seeing it being sliced off the whole sausage. You then had to peel the paper skin off before you could eat it. I'm sure it tasted better then.
OOPS I'm showing my age, again.
