Yes, definitely. Especially if it is organic cauliflower, but even with conventional cauliflower nothing goes to waste. Lots of vitamins and nutrients in the entire head of cauliflower. Chop the core (stem) and incorporate it with the recipe you are using florets in. It gives it a lovely crispy tender texture. Wash green leaves well, chop and add them to stir fries and healthy cauliflower soup along with cut up cauliflower core.
