Preheat oven to 350 degrees. While oven preheats, place all ingredients into a food processor and process until well combined. It's OK if the mixture is not perfectly smooth.
Lay out a nori sheet, and using a spatula, spread 1/3 of the mixture thinly over the sheet getting as close to the edges as possible. I spread it about 1/8 to 1/4 inch thick. Repeat with the 2nd and 3rd sheets.
Place on a rack in the oven and bake for 15-20 minutes. I used a drying rack on top of a baking sheet to make it easy to put in and take out of the oven. Start watching them at 15 minutes so they don't get over-browned.
Remove from the oven and let cool on the drying rack. Once cooled, trim the edges and cut into squares or triangles. Enjoy!!
