Now I know that you can not beat a proper sausage. But my mother is a vegetarian.
Grate some strong cheese and mix with a carton of cream (full fat). Add a grated onion, mustard powder and plenty of pepper. Toast some bread and whizz into breadcrumbs and combine in the mixture too. Get your hands in and make some sausage shaped patties. Roll out pastry (lazy) and line up the sausages (or make one massive sausage along the pastry. Roll and trim. Egg wash and egg wash again. Chop into desired length and bake.
Many non- veggies LOVE these bad boys!
