We like Ruebans and the advantage of making them at home is that youcan control the amount of dressing and also the amount of saurkraut to  use. 
  
 I also use a spicy Russian dressing instead of thousand Island  dressing on mine as Hubby doesn't really like thousand island  dressing.
  
 One thing to remember when  making these ti  to be sure that your kraut is well drained. I even pat mine dry after draing it for at least a half  hour. If you don't then the side that the krout is on the bread becomes soggy even with grilling.
  
 You can buy corn beef and make it for the sandwiches but I have found that buying sliced corn beef is for me a better solution. They are thinner slices than I can make and as far as I am concerned  works better
