Soak the split yellow mung beans in water for 4-5 hours.
At the same time, soak the chopped napa cabbage for 4-5 hours in salt water.
Chop the onion, green onions and kosari into 1-2inch small pieces.
Heat oil on a non-stick pan. Spoon the batter into the pan and spread into pancake shapes. You can use the spatula to shape them into spherical pancakes (instead of amoeba shapes, unless that's what you're going for!) Cook until the bottom looks golden brown, and then flip to cook the other side until both sides are browned.
Best served hot off the pan, or reheated later, with a soy sauce/tamari and a little rice vinegar sauce for dipping. Enjoy!
