Bring on the cauliflower. You want a lot of cauliflower for this dish. First, it shrinks during roasting. Second, it is so delicious cooked this way. As it happened, we had too little cauliflower when we made this. So when we did leftovers, we tossed a can of drained chickpeas with a tablespoon each of gochujang and olive oil, then heated them briefly before adding the leftover chicken and cauliflower to the pan and reheating it. Also seriously delicious.
