Remove the stems from a bunch of green beans. Toss them with oil and salt and arrange them on a baking sheet. Put it in the oven and turn the oven to broil. After 5 minutes, stir the green beans  and return them to the oven. After 5 minutes, check if the beans have browned a bit. If not, stir them and continue broiling for another couple minutes. When they’ve browned a bit, turn off the oven and leave the green beans in the oven for about 20 minutes to finish cooking. They’ll go a bit wrinkly and be nice and tender.
