Scoop out the seeds of a pumpkin and run under cold water.
Rinse the seeds in a strainer. Lay out on a towel and pat dry.
Toss the seeds with olive oil and spread on a baking sheet. Sprinkle with coarse salt and/or seasonings of your choice. Roast in a preheated 350-degree oven, stirring occasionally until they are lightly browned, about 40-45 minutes. Cool and store in an airtight container.
