Makes about 1 cup of dressing.
Toast pumpkin seeds in a dry pan over medium heat until nutty and slightly golden. Remove from pan and cool.
Puree all ingredients in a blender or food processor until smooth. It may be necessary to add a little bit of water if the mixture is too thick.
Dressing will keep for up to a week in the refrigerator. It will solidify, so pull out a few minutes before using to let it come to room temperature.
