Cut the cauliflower into small florets (finger size) not every child will like it, so it's a good idea to keep them small and not waste them. Although the kids who had never tasted cauliflower before we the ones who loved it the most, asking for more and the recipe.  Wash the cauliflowers under water - we found this easier after they cut into pieces.  Keep a few of the leaves, they are delicious when roasted too.  Place on a baking tray with baking paper drizzle with olive oil and sprinkle with salt.
