I also have to pack stuff for work..I went and got snap tight containers and also had some cool packs --ones that you throw in your freezer--and you take out and put in your lunchbag to keep things cool--then I pack romaine leaves and either stuff the romaine with with tuna salad or egg salad, slices of chicken or roast beef...or cheese....makes a great "sandwich" .I also pack hard boiled eggs, individual string cheese packets, sometimes leftover dinner from the night b4. my lunchbag is one of those insulated zip-boxes. have fun! and be creative
