In place of the sunflower seeds, you can also use hemp seeds hearts. We also love the taste of pumpkin seeds (pepitas), but they will give a greenish colour to the blended mixture.And if you don't need a nut free vegan parmesan, you can also use cashews, almonds or walnuts. If you prefer a stronger flavour, increase the salt and garlic powder to taste.Keeps for a few weeks in a jar in a cool, dark place. Store in the freezer for longer life.
