What is for dinner?

My wife is on a fairly strict schedule of exercise and is eating very carefully. She has been working at this for several months. There was a time when she would have turned to the best diet pills to loose weight but that is not the case today. She is now dedicated to loosing weight in a way that will send a good message to our children. The only problem I have with her plan is that she never seems motivated to cook dinner. It is almost as if cooking dinner has completely confounded her. She is able to come up with healthy meals for everything except dinner. I think she is used to cooking heavy meals and simply doesn't know what comprised a low calorie and low carbohydrate meal.
