Morrisons have some great sausages called Harrogates favourite sausages they come on packs of 6 and cost about 1.69 and they are 0.8 carb grams per 100grms and they are really meaty andd tastey!! Sainsburys and Safeway also do a good range of low carb sausages, they are more expensive than your average banager, but I think its because the consist of more meat, instead of the crap the cheeper sausages are filled with.
