Probably.. you open your mouth and chew...
Seriously though.. are you following a Low Carb diet ? If so they you want to get high meat content sausages. Check the labels.. I try to get 97% meat sausages.. don't know where you shop but Waitrose have a brand called Heck that have these in sausage shape as well as square sausage burger type.
Tesco do the same. I had 7 last night and they hardly nudged my FBG this morning at 5.3.
Had some home made ones a few weeks ago from a friend....BOOM! - 7.5 - no idea what she out in them, but they tasted the best sausages I've ever eaten.
Anyway, the 97% supermarket brand is my staple every couple of weeks now
