To make a Parmesan-like vegan cheese, blend either almonds or cashews (and you may even try sunflower seeds, or a combination), with salt and nutritional yeast flakes. Start with about a handful of nuts for a small amount and a pinch or two of salt, and a handful of nutritional yeast flakes. Grind in a blender into a powder. Taste, and adjust as needed.
Not sure about nutritional yeast flakes? You may like to try it without nutritional yeast flakes and with coconut oil and salt and garlic and/or onion powder (optional) instead.
To adjust, if it is not cheesy enough, add more nutritional yeast flakes and/or more salt. If it is not salty enough, add more salt. If it is too salty, add more almonds.
Use in place of Parmesan cheese.
For another Parmesan flavoring, combine coconut oil, salt, onion and/or garlic powder (optional), and lemon juice. Start with a little of the seasonings and add more as needed. This is especially delicious on salads.
