The one thing that has been most helpful for me this year is the Alladin MicroMagic thermal container, which I found at KMart in the camping section. This thermal container is microwaveable and keeps foods very hot for hours. I stick the cold food in it, zap it in the microwave and send it to school. The containers come in 7 oz and 10 oz sizes. I have found Grandma Millina's Organic Pasta-O's (like spaggheti-o's) to be the most-requested lunch for my son. One variety of the Pasta- o's is cheese and milk free. I have been able to find Grandma Millina's at Fresh Fields (whole foods markets) and my local health food store. Lynda
