I know you can do lots of different veg, e.g, carrots, but carrots aren't compatible with LCHF so are no use to me!
Ok I get that carrots are off for some but a little spiralize do carrot goes a long way probably about 1 - 2g of carbs. You say you know you can do lots of different veg so I'm sorry I don't really understand your question. Do you mean can you do other things other than veg?
Things I have spiralize do
Courgette, carrot, Apple pear, peppers, cucumber, cauliflower, broccoli, onion, fennel, cabbage, radishes, sweet potato, small new potatoes, brussel sprouts, beetroot, celeriac, turnip.
The higher carbs ones obviously in smaller portions, but because they are cut so fine they go a long way. I made a fennel and apple coleslaw today to go with a crustless quiche for supper, I used about 1/2 an apple served 2 of us and there is still a portion in the fridge.
The only thing that didn't really work was aubergine it sort of shredded a mushed all at the same time
