Seaweed snacks are incredibly nutritious and can make for a pretty tasty snack - especially for the littlest snackers in the family who will get an extra boost of goodness without even knowing it. Iron, iodine, magnesium and a stack of vitamins are all hidden inside this vegetable of the sea. Add some seaweed snacks to lunchboxes or enjoy crumbled over Asian inspired dishes for a hit of umami flavour.
