Char shared a simple recipe for dried pumpkin seeds....
Pumpkin Seeds
Scoop the seeds out of the pumpkin and take off as much of the stringy stuff as I can. Rinse the seeds and spread in a single layer on a cookie sheet. Sprinkle with salt to your liking. Bake 350 degrees 20 - 30 mins, stirring them a little about half way, bake til toasted light golden and dry. They can have a bit of a chewy, maybe stringy texture. I think it depends on the pumpkin.
