Rinse pumpkin or squash seeds in a colander. Spread evenly on a baking sheet and allow to dry for 1 hour or longer. Pat dry with a clean dish towel or papertowels if desired to save time.
Preheat oven to 275 degrees F.
Toss the seeds in spices and lime juice. Place the seeds back on the baking sheet and roast for 15 to 20 minutes. Remove from the oven, and allow to cool on a plate. Put in a bowl and serve as a shared snack.
