Originated in Asia, cauliflower is something you wouldn’t want to miss out on, as it is high in both fiber and vitamin C, with a half cup of florets providing nearly half the daily requirement of vitamin C. It also contains a fair amount of vitamin A, folate, calcium and potassium as well as selenium, which works with Vitamin C to boost the immune system. Besides, cruciferous vegetables such as cauliflower are touted for their high levels of cancer-fighting phytochemicals known as glucosinolates, so there’s that, too! When it comes to cooking, cauliflower heads can be roasted, grilled, boiled, fried, steamed, pickled, or eaten raw.
