First of all, you will have to rinse well and then soak the mung beans in water for about 4 to 5 hours. After it is soaked well, drain the water and keep it aside for some time.
Meanwhile, take a pot and add some water. Bring it to a boil and cook the mung bean sprouts in boiling water for about 5 minutes. However, you can skip this step of blanching if preferred.
Rinse the mung bean sprouts in cold water in order to stop cooking. Now, drain and simply squeeze out the extra water.
Now, it's time to cut the scallions and kimchi into thin slices.
Next, take a large bowl and add the kimchi, scallions, bean sprouts, soy sauce, pork, garlic, and sesame oil. Mix everything properly.
Add two cups of soaked beans to a blender. Pour 3/4 cup of cold water into the blender with 1/2 teaspoon of salt. Grind until it becomes a coarse, sand-like texture.
Add this batter to the mixture of vegetables and pork. Gently combine the mung bean matter until all the ingredients are distributed evenly.
Take a non-stick pan and keep it over medium to high heat. Add 2 tablespoons of vegetable oil and allow it to become hot.
Take the above-prepared mixture and ladle it into the pan. Spread it evenly into a thin round structure. Cook it until the bottom part becomes golden brown; it might take 3 to 4 minutes. Now, turn it over and add some more oil to cook it properly.
Using a spatula, press it down and cook for another 1 to 2 minutes. Repeat the same process with the rest of the batter.
Serve hot with the dipping sauce.
