My husband refuses to flour or bread anything when he’s seriously dieting; but in my experience, after you get through the initial phase or two of this kind of diet, the carbs added by a little flour are negligible. I think you always have to have balance - and you’re not going to stay on any diet without having interesting things to eat. Once in a while, that tiny bit of flour or bread crumb makes a big difference to comfort.
As an aside, I am going to try to make a pita out of cauliflower and cheese for a pastrami sandwich.
Saw a video last week on a cauliflower pizza crust and I think it can be modified to create a pita.
I want a sandwich, but I don't want the guilt of eating bread.
Quinoa flour works well for a little breading and is fairly low net carbs. Xantham Gum is a good substitute for flour for thickening sauces and is easy to use.
