During my Narita layover, I stopped by a convenience store to pick up some onigiri, which is my favorite Japanese snack ever. It’s essentially a stuffed rice ball wrapped in crispy sheets of seaweed. My favorites are from the 7-11 or Family Mart and contain spicy tuna or tuna with mayo as the filling. You may also find teriyaki beef or plum or whatever, but I love the tuna ones best.In Hawaii, there is a similar rice ball called musubi and, in classic Hawaiian tradition, it’s stuffed with a seared slice of Spam. Why some call it musubi while others say onigiri is unclear—both words refer to the same thing: a rice ball.They’re handy snacks for on-the-go. In Japan, I would buy some in the morning and carry them in my bag for a mid-day snack in between sightseeing. Or they’re good for a road trip or day at the pool. Basically, any food that can be eaten neatly with your hands is the ideal on-the-go snack.After a weekend of hectic home-cooking, you’re probably ready for something simple. Here is an easy recipe for musubi/onigiri. Happy cooking!
