Ummmm....
- open lunch box
- put food inside
- ???
- profit
In all seriousness though, I bought the Canadian Ice Cooler or whatever its called from Strongbags. It works good.
If I were to do it all again, I'd just buy a chart case. When 50% of the hotels don't have freezers, so you got to either put your stuff in the "crew room" freezer only to have it stolen or the company employee freezer it just isn't worth it.
I bid around free breakfast, pack all dry foods and plan to eat out once a day.
