Heat 2 teaspoons oil in a large skillet over medium heat. Add green beans and season with salt and peppers. Sauté for 2-3 minutes until beginning to soften. Reduce heat and carefully pour 1/4 cup water in hot skillet (it will sputter, so be careful of steam) and cover pan with a tight fitting lid to steam for 10 minutes. Monitor carefully to make sure the water does not completely evaporate before the beans have steamed, adding more if necessary so they do not burn.
