Preheat your oven to 250 degrees. Wash your pumpkin seeds off to make sure there is no more pulp left on them. Dry the pumpkin seeds completely. Now, in a large pan sautee the pumpkin seeds in about 2 tablespoons or so of butter and 1 teaspoon of salt. Keep stirring them for about 3 minutes to make sure they are covered in the butter/salt mixture. Now spread the seeds on a baking sheet and bake for about 30 to 45 minutes. Let the pumpkin seeds cool and enjoy.
