this is something that I learned long ago at macrobiotic camp and both my sister and I have tried it and feel that it really does give us more energy for the day ahead! plus, as I have talked about before, your kids will love it too! I have not met a child who doesn't like the taste of toasted nori...it's really funny how that works! I find that small kids who don't question the look of it are very happy to try it...and they always find it delicious (even for babies in very small amounts).
you can purchase nori sheets just about anywhere (but here is a link to the kushi store where you are ensured that it is good and organic). we toast them right on the stove top by turning the flame down to the smallest possible flame (or it works well if you have been cooking and your grill is still hot) just take a single sheet and toast until it turns bright green and you are ready! you can also do this in an iron skillet if need be...the toasted nori will become light and delicate and very yummy! (you can see the difference between raw and toasted in the photo) eat a sheet a day and I think you will feel a difference.
while we are talking about nori, I would also like to mention that it's nice to have the nori around because if you are like us and make big batches of brown rice and you have leftovers the next day it's a great way to make brown rice sushi! just steam your rice to heat it up and fill your sushi with your families favorites (and throw a little piece of umeboshi plum inside for extra yumminess!)..all you need is a sushi mat, brown rice, nori and some vegetables! instant snack or dinner! and kids like to get in on the creating...it's good fun (and just a bit messy)
good luck and let me know if you find yourself with more energy!
