I'm definitely more with Jos here on the cauliflower front. They're just as keto left in nice big chunks are they are messed about with. Steamed cauliflower, lightly salted, is a thing of beauty as long as the cauliflower is (a) firm and fresh, (b) cooked to just the right level of bite. It's also very nice roasted in bite-sized florets with olive oil, green olives, onions, paprika, pumpkin seeds and chorizo slices for half an hour, with a sprinkling of fresh parsley at the end. I tried cauliflower steaks once. Waste of good cauliflower in m'humble. It amuses me to think that anyone would try to make something that isn't rice into fake rice, just because they won't eat the real thing. I once saw some vegan "lamb chops" in a supermarket that were the same shape and colour as real lamb chops. I mean, do me a favour...

Incidentally, smashing your raw veg into smithereens does absolutely nothing for its vitamin content.

Still, whatever stirs yer loins...
