I like to do all my cooking on Saturday/Sunday. I make alot of pastas and soups. I put one - two servings in several disposable tupperwares and freeze them individually. In the am, I take my little lunch box thingy, put in my "home-made" frozen dinner, some apples, nuts, grapes, and other snacks. It not only keeps the other stuff cold, it thaws after about 4 hours, just in time for lunch (no refridgeration necessary).

Good luck!!!!
