Place chickpeas in a bowl and mash them with a fork, leaving some bigger parts for more texture.
Blend the nori sheet in a high-speed blender until you get nori flakes. And add it to the chickpeas. Add the rest of the ingredients and stir until well combined.
Serve on its own, or a filling for sandwiches and jacket potatoes. Store in the fridge for up to 4-5 days.
