Hi first post but long time lurker.
I've been having them the last couple of months, mainly the noodles, rice and fettuccine I was a bit dubious when I first came across them as I thought how the hell can they only be 9 cals/21 cals per 100g (some packets say 9 and others say 21 not sure why as they look and taste the same) Prior to having them I barely ate carbs but missed having pasta etc so I thought I would give them a go and I think their great, I haven't put on any weight and they leave me feeling fuller for longer.
On the downside they have an awful fishy smell when you open them and have to rinse them for a couple of minutes before cooking, thankfully they don't taste how they smell! They don't have quite the same texture to normal pasta, rice etc their a bit rubbery but I don't mind that. Their pretty tasteless but you can just add a bit of sauce as you normally would to pasta.
I've just ordered a load more from H&B as their half price until tomorrow and it's free delivery on orders over £15.
