I have lately started snacking on roasted seaweed. It is quite popular in Japan.
One of the things that struck me about it is the size of the package: only five grams. It comes in nine sheets that are about 6 by 9 cm each.
Eating it one sheet at a time, I have noticed that a lot of my eating of snack foods has been rather automatic: just stuffing it in. This is important to me since I need to lose some weight. I hope it is useful to you.
