Soak the rice cake slices in cold water to soften.
Cut the beef into bite-sized pieces and marinate with minced garlic and soy sauce.
Put the beef in a pot and stir-fry, then add water and bring to a boil.
When the broth boils, add the soaked rice cakes and continue boiling.
Once the rice cakes become soft, season with soy sauce for soup and salt.
Beat the eggs and add them to the broth, stirring gently.
For garnish, add green onions and dried seaweed flakes as desired.
