Cut the rice cakes, fish cakes, and green onions into bite-sized pieces.
Boil the eggs and peel the shells.
In a pan, add water, gochujang (Korean red chili paste), gochugaru (red pepper flakes), soy sauce, sugar, and minced garlic, then bring to a boil.
Once the sauce is boiling, add the rice cakes and fish cakes and boil.
When the rice cakes become soft, add the boiled eggs and green onions, and simmer once more.
When the sauce becomes slightly thick, turn off the heat and serve in a bowl.
