The Japanese love their Musubis. Like sandwiches, they're great picnic and on-the-go snacks.
Oms/b in NYC is helping to spread the Musubi culture in the States. Until they have one out in LA, I'll be making my own:
Ao Ji-so and Shiba Musubi
Wasabi Furikake Musubi
Salmon Musubi - my favorite
Wrap them all in seaweed, and you're good to go. I also made a dill red potato, red onion, and green onion salad (also a good picnic food).
