Cauliflower is edible only if it's been boiled to death and served with buckets of salt and gallon jars of Velveeta. Even then it's a bit suspect. Same with broccoli. Those are two of the three veggies I absolutely cannot and will not eat raw (mushrooms are the other).

The fact that kosher laws are economically obsolete is one of the best explanations I can think of for why American (read: Reform) Judaism decided to give them up. (They hadn't yet figured out that cheeseburgers are delicious.)
