On an aggressive version of Atkins here, doctor monitored (not initiated) minimal/zero carbs and 21 pounds shed in 5.5 weeks, come to a wee plateau though........cutting back on the wine (no beer or dessert wines allowed as they have too many carbs) - even though that has helped me stay sane.
Thank God for celeriac and swede as a replacement to potatoes....easy to prepare as a mash - peel, cubed roughly, boil for about 15 minutes, purée (I use a mouli), a good dollop of butter, lots of seasoning and one can add things like shallots, spring onions, chilli, paprika etc etc.....
I also braise chicory but then I lived in Belgium and love it - split a chicory in two, season it, olive oil over it and in the oven for 40-50 minutes, to the point it is just caramelising. You could put beetroot in along side, I like those with some ginger, horseradish or chilli mix over them, even basalmic vinegar is good....
