In a medium bowl, smash the chickpeas. You can do this a few ways: with a fork, by hand; slowly pulsing with an immersion blender; or a few pulses in the food processor. You still want to leave some texture to it, it shouldn't be as creamy as hummus.
Once mashed, add the rest of the ingredients, including the minced nori sheet. Season with salt and pepper to taste.
Chill and serve with crackers, as a sandwich, or on a salad.
