A popular snack, side dish, lunch box item, or quick meal: Korean Triangle Rice Balls. Also called Samgak JumeokBap, these compact balls are a satisfying and delicious combination of rice and kimchi. Easy to pack and easy to hold, these dense little rice balls are also easy to prepare. To add a little decadence, place a cube of cheese in the center. Air fry until molten and gooey. YUM!
