First throw all the seeds into a large bowl and fill it up with water. Sift through the seeds and pull out any chunks or strings of pumpkin flesh. Once all the non-seed material is removed, drain the seeds through a strainer and pour them onto a baking sheet. Use paper towel to dry them off.
Set the oven to 350F. Drizzle some olive oil onto the seeds, along with a generous helping of salt, pepper, 1 tsp of ground cinnamon, and a dash of paprika (do not use smoky paprika!). Mix well and then redistribute into an even layer on the baking sheet. Place in the oven and bake for 35 minutes, until golden brown. Allow to come to room temperature before serving.
