As long as it's rinsed and cut into small enough pieces, why not? I used to make a blend of rodi water, nori, garlic, salmon, mussels, shrimp, tuna, and squid in a food processor. I would do just a few quick pulses and pour it into a Pyrex. After it was frozen, I would slice it into cubes. Then I would carefully remove them and store them in a container in the freezer. Many people would add suppliments to this mixture. Give it a try!
