Get out a small bowl; using your hands, pull out all of the seeds from the pumpkin. Really run your fingers through the strings to make sure you get out all of the seeds. Once you have removed all of your seeds, place them into a colander and rinse them off with cold water to get all of the stringy bits off. Once that is done, dry off the seeds with paper towels.

Line a baking sheet with parchment paper. Place the seeds into a bowl and mix with the olive oil, making sure to coat the seeds well (but you do not want them to be greasy, hence the small amount of oil). Spread the seeds evenly on the parchment paper.
