Personally, I need some sort of starch at lunch, and some protein, and wheat thins, maybe I'd switch those out for rye crackers? You could eat more rye cracker for the same calorie count, and skip some of the sodium and fat.
I make bento boxes for my lunch. I recommend it--the boxes are cute, and lunch is like opening up a gift, just for you. What I usually pack is brown rice (I have a rice cooker, and I freeze extra), some protein--it might be leftover chicken or pork or beef, or a Japanese rolled up omelete (tamago) or a couple hard boiled eggs, and then a couple types of vegies that I cook up in a larger batch perhaps or cook really quick in the microwave.
The one downside to using a bento box is that they pretty much aren't big enough for a real salad based meal, so it won't work for those who like salads for lunch. A good website for bento ideas is: http: www.justbento.com/
. One can use different sorts of plastic boxes as bento boxes as well--the ones at Ikea are nice.
