I make pasties with a tin of corned beef cut up into small cubes.
Potato, swede, onion as well all cut into the same size cubes (about 1/4 inch)
mix should be around 80% veg to 20% meat. Plenty of black pepper and a couple of beef stock cubes all mixed together well for the filling. I get about 20 large pasties from a tin of corn beef so it is a cheap dish. Just time consuming to cut everything up into the small cubes. The secret is to cut it into cubes, mincing up the filling is a lot faster but it just does not taste or look the same. I don't cook the veg before as in the 'Bikers' recipe just cut it all up raw. ( of course the beef is cooked anyway)
