1 lbs green beans, trimmed
1 Tbsp olive oil
Coarse-grained sea salt or kosher salt
Preheat the oven to 450 F. Lightly grease a large sheet pan or shallow roasting pan with oil.Arrange the green beans in a single, uncrowded layer on the prepared pan. Drizzle the oil over the beans and roll the beans until they are evenly coated.Roast for about 15 minutes, or until the beans are well browned, shaking the pan occasionally for even cooking.Transfer the beans to a shallow serving bowl or platter and sprinkle with the salt. Serve immediately.
