The complaining amongst the kids would be my main reason for not doing it. If you think meals are a hassle now just wait - they would get a lot more difficult. What might be better is to rethink what you are serving. No matter how nutritious a food is if no one will eat it then it is off the menu. Keep it simple. Noodles cost only cents. Boil, add a bit of margarine and they will eat as is or add a spice - mine like celery salt on them to kick them up a notch (seasoned salt, garlic salt, etc.). Don't make extra work for yourself if you are not getting the response from the kids. That doesn't mean switch to a diet of cookies cause they will eat them but frozen mixed veggies for example work wonders. They can pick out the kinds they like and leave the ones they don't. Again toss in boiling water and you are done. No prep time. Make extra food when you cook suppers and some of that becomes lunch the next day. Again not a lot of extra time required.
