I agree with Mouse. It's far better to take those overly salty products off your shopping list and cook from scratch. OK in an emergency, they can be useful (opt for lowest fat, lowest salt you can find - cos they can cause water retention), but at the outset best start as you mean to go on! And of course it's not the fact that it's wafer thin that doesn't mean they've not added other non Dukan nasties to it, so check the "ingredients"!
Good luck!
