This delicious recipe came from a class I took at my local food co-op on sea vegetables by Nishanga Bliss. It is super easy to make and is wonderful for people who have not done a lot of cooking with or eating of seaweed, like me. I served it as a side to veggie burgers and ate leftovers cold in my lunch the next day. You will probably be able to find the seaweed in natural food or Asian stores. Variations: use almond or peanut butter instead of tahini, add garlic while cooking the onion, add whole toasted sesame, pumpkin or sunflower seeds.
