Preheat oven to 400degreesF. Wash, dry well, and trim green beans. Put green beans on a jelly roll pan. Drizzle with olive oil. Sprinkle with salt and pepper to taste (I like them salty so I use about 1 1/2 teaspoons of salt and about 8-10 grinds of the pepper mill). *Mrs. Dash may be substituted for salt and pepper as desired. Use your hands to be sure all the beans are evenly coated and spread them out into 1 layer. Roast for 20-25 minutes, turning after 15 minutes, until beans are fairly brown in spots and somewhat shriveled. Serve hot or at room temperature.
