Meat-Free Sausages

I got a discounted voucher from Holland and Barrett.  Discount on one item at full price.  It was a difficult challenge!  A lot of items are already on discount.  A lot of full priced item are overpriced.  After 30 minutes at the shop and searching on the internet, I opted for the meat-free cocktail sausages.

The cocktails sausages are quite good, and quite filling.  But I don't understand why they are so calorific.
