Cut the beef and various vegetables into bite-sized pieces.
Pour water into a pot and boil it with kelp and other broth ingredients to make the stock.
Once the broth starts to boil, remove the kelp and add the prepared vegetables and mushrooms to cook them in the broth first.
When the vegetables are moderately cooked, briefly dip the beef slices into the broth to cook them shabu-shabu style.
Dip in sauce and enjoy.
