Do you have a picky eater?

As a busy mom of 3 who works and goes to school I am constantly involved in a battle with food. I want to provide my kids with healthy food, but sometimes convenience can help with my busy schedule. My biggest dilemma is that one of my fabulous children doesn't eat anything. If it isn't a chicken nugget, pizza, mac and cheese or peanut butter and jelly she won't eat it. It is a constant battle with her and there have been many nights where she has gone without dinner because I will not give in and make her a special dinner. So I need some ideas. Luckily, my other two aren't as bad and they are at least willing to try the foods I make and that is all I really ask for. So I need some ideas or options that I can offer to my family that can satisfy my picky eater. So share with me and my readers some ideas to get new foods in my menu.
