Our family loves sushi! Sushi is a very healthy snack or lunch, but it can be expensive. Making your own sushi is a fun and easy alternative to the expensive store-bought sushi. Nori is famous for its role in making sushi rolls (it is the green part of the sushi). It contains nearly 50% balanced, assimilable protein, and is rich in calcium, iron, phosphorus, iodine and carotenes.
