If you're spending time in the kitchen anyway, there's no better food to ensure that you get the most bang for your buck than soup. A big pot will serve your family for a few nights, and if you make a double batch, it freezes beautifully. All of these recipes are customizable to suit your kid's tastes and can be served on their own or turned into a heartier meal with the addition of a sandwich or salad. Bon appetit!
