Fill a pot with 2 to 3 inches of water. Set a steamer basket on top so the basket sits above the water inside. Bring the water to a boil over high heat. Lay the baby broccoli in the steamer basket and place the lid on top. Steam the baby broccoli for 2 to 3 minutes, or until the stalks and florets brighten in color and become tender. Serve warm. Wash and trim the stalks.
Cook, stirring occasionally, until broccoli wilts. After 3 minutes, add the remaining tablespoon of oil along with 1 tablespoon of water and salt and crushed red pepper to taste. Add an additional tablespoon of water ever 3 minutes or so, stirring each time. Cook broccoli rabe for about 20 minutes total or until it is very, very wilted.
