Roast Sunflower Seeds

Harvest and roast sunflower seeds when they are brown and slightly dry. Place cut sunflower heads in a brown bag and store in a cool, dry location for two weeks. Remove the seeds from the heads and place them in a cookie sheet. Roast them at 200 degrees for up to three hours. You can grow own sprouts with this fun activity.
