Wash beans, pat dry, and remove tips and tails.
Heat 2 teaspoons of olive oil in good sized fry pan on medium heat. When the oil starts to move easily when you move the pan, add beans and gently stir once or twice.
Cover beans and cook about 2 minutes. Stir, cover and cook another 2 minutes. Repeat until beans are almost, but not completely, to the softness you desire. Some will get a bit browned as if you were cooking on a grill. If it happens too quickly, reduce the heat.
When beans are nearly to the texture you like, add the remaining olive oil and the marjoram. Stir to distribute marjoram among all the beans. Cook uncovered for ~1 minute. Remove from heat and serve.
