I know how hard it can be, I was having to cook 2 meals with my dh, He is a carb Monster (although he has now been on the diet just over a week!!) I am not going to say will power because everybody is different and if we all had will power so strong none of us would be over weight!!
There is not a lot of veggies or salad I do like so i concentrate on what I do, jazz them up with melted cheese or a knob of butter (veg) salads loads of mayo and greated cheese. even if you have to eat before your hubby whilst his is cooking, if your full enough it wont be tempted. Get him to tast food to see if it is cooked or to his liking after all its him thats gonna be eating it!! (or better still get him to make his own lol)
At the end of the day there is only one person who can make you sucseed or fail on this WOE and thats you!! SO GO FOR IT!!

GOOD LUCK
