In a small skillet over medium heat add 1/2 tablespoon olive oil. Add the pumpkin seeds and garlic and cook, stirring, until the seeds start to pop a little (2 minutes). Remove from heat and let cool.
In a blender or food processor add in all of the ingredients including the other 1/2 tablespoon of oil and the cooled seeds and garlic. Puree until smooth (or you can leave it a little chunky depending on your pesto preferences :)).
