Usually I cook/prepare the night before and pack in the morning. Yayoi-san got us a bag of Swiss meat balls from IKEA which is really convenient and tasty. When I'm in the mood, there are about 3 main items such as meat, vegie, and egg cooking. Sometimes I just have 1 main dish like curry rice or pasta bolognese - and an apple for Matt.

I have forgotten how enjoyable Lunch time at work is. (I know, even in this so called Singapore's food paradise, it can get boring and sickening when it's every day). I don't mean to be arrogant but it's far better than eating at hawker center, for obvious reasons, but one thing I didn't know which i realized, is how effective presentation of food is. ... or is it just a Japanese thing?
Anyway, Matt can't wait and usually has lunch before noon time :) - that should be a good sign!
