I've fallen in love with the seaweed salad from a local Japanese seafood buffet. What would be the most cost-effective way to obtain this kind of food in large quantities for regular eating? I would assume that making it fresh would be the best way.
As far as obtaining ingredients, I'm located on the east coast of the United States; so this isn't a native dish.
I'm also confused on the type of seaweed to look for. Google says that I'm looking for wakame seaweed but search results show many different varieties.
The specific type of seaweed salad I want appears to be "sesame seaweed salad".
Here is a photo of what I would like to make:
