Topic: Low carb BIR - is it possible?

[Sverige]

So Wifey mcWife-face put herself on a low carb diet again but as usual it seems it's up to me to find meals to cook each night and I got to wondering whether BIR curry might be ok. Onions, which make up the bulk of our curry sauces, seem neither very high or particularly low carb:

Veg oil is fine, as fat seems to be positively encouraged on a low carb diet and I can always omit the already tiny proportion of peppers and potato from the base gravy I cook, so what do you reckon? Spices and coriander I'm assuming don't have carbs.  If the finished curry doesn't have any sugar or coconut flour, etc added I reckon it could be a viable low-ish carb option, served up with cauliflower rice, because for sure white rice is out of the question.

Just wondering if anyone is well up on diet and nutrition questions...?
