You'll need:
Pumpkin seeds
Olive oil or melted butter
Salt
Start by rinsing those seeds and removing any pulp, and then spread them out on paper towels to dry over night. The next day line a jelly roll pan or cookie sheet with raised sides with foil and preheat the oven to 250. Toss the dry seeds with the olive oil or butter, then salt and toss again. Spread the seeds out on the foil covered cookie sheet and bake for 1 hour, rearranging the seeds every 15 minutes.
