Why the peculiar name? Well, I must admit there is a reference there, but it does make an appropriate name for a futomaki that has lots of ingredients. Most of the colour of this lunch depends on the contents of this roll.
Top tier: ‘rainbow rumpus’ rolls (crabstick, carrot, cucumber, chives, sesame seeds, benishoga, spinach namul, shredded chicken, simmered mince beef, sriracha) on sorrel.
Bottom tier: tamagoyaki, lumpia, soy sauce fish, broccoli, more sushi.
