Have you tried cauli rice at all? It's amazingly effective, in terms of adding texture and bulk to a meal, without adding significant carbs. Alternatively, if I can't be bothered to do the cauli, I just have the curry/chilli or whatever in a bowl and tackle it with a fork and spoon, like a very substantial soup/stew.
I can actually cope with rice, but in fairly modest portions. Sometimes I just can't be bothered to cook a little rice, so I just don't bother.
Part of the acceptance of this thing is finding ways to eat some of what we like. Often it isn't going to be the same as before, but it doesn't necessarily mean things are completely off-limits, just because we can't hack the accompaniments.
