KETCHIKAN, Alaska -- Your idea of seafood probably isn't seaweed. But Dolly Garza would like to change that.

She is a professor at the University of Alaska Fairbanks and is the author of a new book which includes seaweed recipes.

Garza says seaweed is low in fat, has lots of vitamins and minerals, and harvesting it is a great family activity.

Garza is especially fond of dry seaweed.

She says the easy way to eat seaweed is to roast it and munch on it like chips.
