That’s cool that you have a pool. Here, it’s too hot to even go outside unless there’s water around. I was thinking about the same lunch issue, and this is what I came up with. I was on Amazon’s website and saw cookware that collapses and seemed very useful. It’s called a Foldtuk.. figured I would give it a try. So, I baked some dinner in it, put it in the fridge, and then could heat it up in the micro (I know they have one at my school). When I’m finished, I just collapse it into my briefcase like a disappearing lunch box. Maybe this is something that will help you eat more interesting foods from home. I like doing baked pastas and casseroles.
