For a tasty snack, toast the seeds from butternut squash. Heat oven to 275°. Wash the seeds in a bowl of water to remove seed fiber. Drain the seeds and remove any remaining bits of flesh or fiber. Spread on a cotton dishtowel and allow to dry. Place seeds in a bowl, add olive oil to lightly coat, and salt. Place seeds in one layer on a cookie sheet and toast in warmed oven until seeds brown, about 10 minutes, checking doneness by taste.
