The other thing I use for a very similar salad is Quinoa(pronounced keenwa), it has more flavour than couscous. It has a slightly nutty flavour and is delicious used to make a tabouli with lots of lemon juice and parsley. Or you could put in the roast veges and make your own egg mayonnaise or ceasar dressing which is really simple and put a dollop of that on.
We are in to week 4 and for the first 3 weeks I managed to put on weight, I am pleased to report that I have just lost some, not much but its a start. My husband on the other hand has lost about 3 kg. Its great looking on the website and getting lots of ideas and support. Good luck
