Cook corned beef according to THIS recipe and strain and reserve broth.
Shred or dice the corned beef once cool.
Add 1 box of beef or chicken stock to your corned beef broth (if you didn’t reserve broth from cooking your corned beef, simply double the boxed stock).
Add your carrots and potatoes to the pot and bring to a boil. Reduce heat and let simmer for 20 minutes.
Add the cabbage and let simmer for an additional 5 minutes, then serve!
