Basically you take a whole head of cauliflower and blitz it in the food processor. You can cook it in a pan, or I added a touch of water, covered the dish and steamed it for a few minutes. Having a canister of the cauliflower prepped and ready in the fridge has been great. This morning I had a leftover veg dish from Ottolenghi, topped it over cauliflower rice and added a couple poached eggs. Depending how far you cook the 'rice', it also has a bit of texture like a chopped nut. Since it's already prepped, I find myself adding it to soups, salads, etc.http://www.thekitchn.com/how-to-make-cauliflower-rice-couscous-cooking-lessons-from-the-kitchn-203344
