I have 9 hours of college classes in one day this term, and the food on campus is AWFUL, so I want to get myself in gear and start doing a proper bento type thing so I'm not starving and end up hitting up vending machines for food. The catch is that I need something easily portable that will actually hold either two reasonably sized meals, or a decent meal and a couple of hearty snacks. (I can always get something to eat when I get home late, if I haven't had enough, but I need to at least be not actually distractingly hungry, you know?)
