I also like using kelp or other seaweed powders with my grains when I cook them, either alone as a salt replacement or with other additives like various spices, herbs, oils, etc. Possibilities pretty much endless.
Lately, have been doing a lot of experimenting with adding coconut cream to this, both as hot and cold dishes.
Kelp can also be added to any of the many traditional green sauces made with fresh high quality in season herbs and high quality oils or nuts. Can produce a very fine vegan pesto sauce this way, leave out the cheese that is often included yet have similar flavor.
