CUT the nori with scissors into 1" wide strips and then cut them in half so you have a bunch of 1"x4" strips. Keep them dry until you're ready to use them.
Place one (shiny side down) on a dry surface and place a piece of bell pepper across it near the bottom so it forms an upside-down crucifix (this is not an antichrist meal, it just works best like this)then pile on the avocado, sun-dried tomato, pickled ginger, or what-have-you in the same fashion. Stick a SMALL chunk of jalepeno in there somewhere. Place a small sprig of cilantro (this is VERY important) so that it may stick out once it's rolled up.
Now just tightly roll it up away from you and seal it with a nama shoyu moistened finger and place on a platter seam down.
