Edible pumpkin seeds - also called pepitas - are a popular ingredient in among others Mexican cooking. With their white hull removed, they are a medium-dark green and have a deliciously delicate flavor, which is even better when the seeds are roasted and salted.
Pepitas are sold salted, roasted and raw, and with or without hulls. They're available in health-food stores and many supermarkets.
The seeds are also used to make pumkin seed oil. The dark green coloured oil makes a great alternative to for example extra virgin olive oil used in salad dressings.
