Add all the ingredients to a small food processor and pulse in 5-second intervals until it has the texture of grated parmesan cheese, or until you reach your desired consistency. It can be finely grated or coarsely grated but try not to over-process.
Store in an airtight container in the refrigerator until ready to use.
Notes
Salt - If you are vegan, you can use iodized salt to help fulfill your iodine requirements, but you can also use the salt of your choice. You can also adjust the amount of salt to your personal preference.
