Our local Safeway recently transformed into a Somerfield, so I went to see if they had any sort of low carb foods that the other supermarkets don't do. The one thing I found was Somerfield So Good brand Somerset Chedder Cheese and Bramley Apple Sausage. They're around £2 for a packet of 6. They have 2.1 carbs per sausage. (By far the lowest of any cheese and apple sausages I've seen.) They're delicious!
