Glamorgan sausages

Easy and simple veggie sausages, based on a traditional recipe. Great for barbies.

Heat butter in a large pan, add chopped leeks and fry until just softened. In a bowl mix together the potatoes, cheese, herbs and mustard powder. Add the leeks and season well. Add the egg yolk to bind the mixture together and divide the mixture into eight. Shape each into a sausage. Roll the sausages in flour egg white and then toasted breadcrumbs. To cook, fry the sausages for 5-10 minutes until golden brown on all sides. Can be served hot or cold.
