Bulgogi was what inspired this. It's a typical Korean dish mainly made with grilled meat. I often buy a bulgogi tuna as a quick snack when I'm hungry and it looks like a Californian roll with seaweed wrapped around rice and has spicy tuna in the middle. It's good. With this idea, I decided to make rice balls. And it had only six ingredients. Rice, shredded seaweed, tuna, sesame oil, salt and gochujang (Korean spicy red bean paste). You mix these and roll into balls. Refrigerate to cool. Eat when hungry or just eat.
