I have just spent 20 mins writing my Sainsburys shopping this from this thread !!! Its fab !!

Also at Sainsburys from their "Taste the difference" range-
6 Ultimate pork sausages:
5.2g of carb per 100g
Pack is 400g for 6 sausages....so 3.5g per sausage !!
They are yummy, pricey at £2.29 per pack but lovely for breakfast with bacon and eggs !!

6 Pork and leek sausages:
Only 2.2g of carbs per 100g
....so 1.5g per sausage (6 in a pack as above)
these are really yummy

Rowntrees sugar free jelly crystals has a trace of carbs per pack, watch out though as some flavours have more carbs, blackcurrent is my fave at a trace of carbs.
