If you don’t have kale, I think the filling in this recipe will work just as well with cabbage if you reduce the water and the cooking time a little.
We stopped in at a fish shop on the way home from visiting our daughter at the coast yesterday. I had just bought a half kilo of squid, thinking calamari, when I noticed they had snapper frames at a ridiculously low price.
Nowadays I quite often make a meal that features vegetables as the main, not the side dish, and I very rarely use any water that will be drained off. If you garden, fresh vegetables are so gorgeous that it is hard to improve on just serving them as themselves.
