This recipe does not pretend to be anything but plain and fairly bland, like mashed potatoes. It is absolutely ideal for diabetics, kids, invalids and people who need to lose weight, as it can be used instead of a carbohydrate side dish. It is filling, but low in calories and starches, and combine two nutritious veggies in one dish. You can add your own mix of seasonings to the puree -- mine's what I used, and are only suggestions. I am indebted to the cauliflower puree recipes on Zaar, for the idea. It's ideal to serve with strongly-flavoured, sauced chicken dishes. It's so easy to boil baby potatoes as another side, and to add a mixed salad for starters. I did not add butter or any extra fat except that mentioned, and even that can be left out. And this is a large recipe, as I wanted to freeze half. You could halve the recipe for 3 - 4 people. Cooking time is mine: I left it to steam with the lid on and went about my business.(ADDED on 27.1.09: I made it tonight without the spinach, but with about 1 cup roughly-chopped Italian parsley and 1 cup chopped spring/green onions. Just as delicious, and myyyy, what a way to trick a dieter or a kid into thinking it's mashed potatoes! :))
