Clean and cut the rice cakes, fish cakes, and vegetables into bite-sized pieces.
Add water and Yupgi Tteokbokki sauce to a pot and bring to a boil.
Once boiling, add the rice cakes, fish cakes, and vegetables.
Stir well to make sure the sauce coats all the ingredients evenly.
Simmer over medium heat for 10~15 minutes, stirring occasionally until the ingredients are cooked.
Finish by adding cheese or your choice of additional toppings.
