I'm not much of a fan of raw broccoli personally. If I am eating it raw, it's usually only if it's being dipped in some sort of high fat dressing such as Blue Cheese - which kind of defeats the purpose. Steaming is one of the healthiest ways to cook it without really losing too much in terms of nutrients. One of my favorite ways to eat it steamed is with some sea salt, cracked black pepper, lemon zest and a light drizzle of olive oil.
Gordon Ramsay also had a really interesting recipe for broccoli soup that uses very few ingredients, and incorporates the water the broccoli was cooked in, so you are getting all of those leeched nutrients back into the meal. Basically all he did was boil some broccoli in a limited amount of water (seasoned well). Then he transferred the cooked broccoli to a blender to puree it, reserving the cooking liquid in the pan. He added the pureed broccoli back to the liquid and seasoned it with salt and pepper to taste. To plate, he put a pieces of Goat Cheese in the center of the plate, then ladled the soup over it. The cheese melts into the soup and completes the dish. It's vegetarian and only like two ingredients - can't get much simpler than that. The video of him making it is on Youtube.
