Preheat oven to 350°. In a medium-size bowl, toss seeds in oil to coat. Spread on a rimmed baking sheet and sprinkle with salt. Bake about 10 minutes and stir. Bake 5 minutes longer, or until lightly toasted. Transfer to a large shallow plate to cool before serving.
If you prefer, you may toast seeds on the stovetop. Warm a large cast-iron skillet over medium heat. Add oil, then seeds, and stir well to coat. Spread mixture in an even layer; stir often until seeds are lightly toasted. Season with salt. Transfer to a large shallow plate to cool before serving.
