Submitted by blucoat

"This recipe is a lighter version of one that appeared in Bon Appetit (March 2007). You reduce a lot of calories and fat but retain all the flavour! You can also sautee and sprinkle in other veggies like mushrooms or spinach. To save time, this recipe can be made 1 day ahead. Cover and chill cauliflower and onion separately. Time doesn't included 15 minute cooling time."
