One of the things that I don't like about the Laptop lunch boxes is the lack of a thermal option. I know that they sell thermal jars with a strap, and I actually really like the idea of a strap, but I've heard over and over again that their jars leak and can easily get water trapped into the inside. So unfortunately there are some days when we have to leave the inner case at home and send the Thermos FUNtainer jar similar to this. These work really well if you fill them with hot water and let them warm for at least 10 minutes before you put the food in. I've also found that food reheated on the stove retains it's heat longer than food reheated in the microwave. I have no idea why, and I have no scientific facts to back that up, it's just been my observation. For dinner on Thursday I made a huge pot of Mexican Beef & Bean soup. They had leftovers with quesadillas, and organic yogurt.
