These are kimchi pancakes made with a mung bean base as oppose to flour and egg. This recipe is very common among Korean street food. It was adapted from a recipe from Kimchi Chronicles, but additional ingredients were added to really amp up the flavor.

In blender, add drained mung bean mixture, half the kimchi, half the scallions, kimchi liquid, fish sauce, soy sauce, sesame oil lemon juice, salt, and water. Pulse until mixture is fairly smooth with some course bits still inside. Transfer to a bowl and fold in rest of the kimchi, chopped scallions, and sesame seeds.
Heat a couple tablespoons of vegetable oil in a skillet over medium-medium high heat. Ladle batter into pan 3-4 inches in diameter. Fry 2-3 minutes per side depending on heat of your stove.
Garnish with scallions sliced on a bias and serve with soy sauce.
