Cut the broccoli into fairly large flowerets; peel the stems and cut into spears or rounds. Steam it, and while it steams prepare the rest of the ingredients. When the broccoli is cooked, warm some water in a large pan and add the sliced garlic. Then add the steamed broccoli, peppers, marjoram, and parsley. Saute over lively heat until everything is warmed. Serve warm.
