Buy a solar oven! I've searched to find the most cost effective way of cooking for single moms (and everyone else!). These are a good price & work really well! Email me for a flyer. I sell the SOS Sport & Global Sun solar ovens. Prices include shipping to your door. https://sites.google.com/site/singlemompreparedness/solar-ovens.
