Now a true British Sausage Sandwich would be Cumberland or Lincolnshire sausages on a floured bap with ketchup or brown sauce. However, this being Thailand, floured baps are quite scarce in a province where there is very few westerners, but I do make some excellent Cumberland sausage so that part is possible for me. But, I am going to make these with a bit of a twist. Here is 3 versions for you to enjoy.
If making the Cumberland or Italian sausage yourself, this is a Low cost sandwich, if buying the sausage, this could be Fair to High priced per sandwich. I will mark this one as Fair priced for now.
