Toast the sunflower seeds in a dry frypan (skillet) over medium heat, stirring often, until the sunflower seeds are golden brown. Remove from the heat and set aside to cool.
Put the toasted sunflower seeds and the remaining ingredients into a blender or food processor. Pulse until the mixture is a coarse powder.
Store in a jar or airtight container. Sunflower seeds have a tendency to go rancid over time, so use the sprinkle within a few weeks while it's still fresh.
