For the roasted pumpkin seeds, cut a hole in the pumpkin around the stem. Then scrape all the seeds and as much as possible of the pulp from the pumpkin with a spoon or knife.
Remove the seeds from the pulp, place in a bowl and mix with about 2 tablespoons of oil. Then place on a baking sheet lined with baking paper.
Bake in the oven at 180° until they have a brownish color. While they are still hot, sprinkle the roasted pumpkin seeds with salt.
