There are a few different ways you can make this very simple alternative to grain based couscous or rice.  Wash the cauliflower or romanesco and break the florets apart.  If you do not have a food processor you can grate it on the large grate side of a box grater.  If you do have a food processor you can either fill the bowl about 1/2 full and pulse until the florets are broken down to the very small size of couscous OR you can use the grater attachment and run it through there.  This can be used raw in a salad or cooked either by steaming in a steam basket or put enough water to cover the bottom of a skillet.  To the skillet add a little olive oil or butter, salt and pepper if you like, the “couscous”, then cover and cook until tender, about 5 minutes.  You can toss the cooked couscous with butter, finely chopped parsley or cilantro, or toss in toasted almonds and a handful of raisins.  Just a note; the grated cauliflower can be frozen in an airtight container to save for future meals.
