Personally I am having corned beef and cabbage, I have to.
But I have made with leftovers a corned beef salad, with romaine, sauerkraut, corned beef, some dressing thousand island or russian, some onions, carrots shredded.
It is good and I do enjoy it on a later date. But ... What else do you like with corned beef or do you make anything different on St. Patty's day.
FYI: I do actually put green food coloring in my beer, just for tradition.
