I apologize if this has already been done before, but I was merely curious:

What do each of you eat for lunch during the days you commute?

Do you pack lunches?

Are there any types of food you feel you must have/must avoid?

What methods of packing/transport do you use, if you pack a meal at all?

I myself typically use a Mr Bento and bring some basics with me...boiled eggs, small salad, carrots, small bowl of soup...perhaps even a few sweets, as well.

So, how about it, fellow commuters? What's your food for the road?
