In a medium bowl, mix together the seeds, vegetable oil, sugar, and salt. Toss until the seeds are well-coated.
Take a cookie sheet and line with foil... Grease it well
Place the seeds mostly a single layer if possible
Bake at for 45 minutes to an hour kinda depends on the size of your seeds, stirring every 10 minutes or so, until the sugar and some of the pumpkin seeds have browned.
Remove from the oven and let sit for about 10 minutes . After 10 minutes, remove from the cookie sheet and spread on a sheet of parchment paper, separating the seeds from one another as much as possible. Some of the seeds will stay stuck together but thats ok.
