Toast pumpkin seeds on stove top without oil (I prefer using a heated iron skillet). Stir/shake regularly until you smell the seeds toasting. Remove and food process with the rest of the ingredients. Add high quality olive oil and/or water while processing until you reach the consistency you desire.
