This recipe is a tasty excuse to eat a lot of parsley.
"[Parsley] derives its name from the Greek word meaning "rock celery" (parsley is a relative to celery).
Parsley contains three times as much vitamin C as oranges, twice as much iron as spinach, is rich in vitamin A and contains folate, potassium and calcium. What's more, parsley is also recognized for its cancer-fighting potential. "
And seaweed:
"Nori is about 1/3 protein and 1/3 dietary fiber. It contains high proportions of iodine, carotene, vitamins A, B and C1, as well as significant amounts of calcium and iron."
