Whenever I don't know what to take to work, I like stir-frying all Asian-flavour compatible veggies in my fridge and wrap them up in rice paper. My favourite dipping sauce is a bought one called "Sweet-sour sauce for chicken"... but it's great with anything!
Another thing I have wanted to try for ages is General Tao's Tofu of vegweb. I used arrowroot powder instead of cornstarch to thicken the soup, and though I was very critical towards it because I've grown up with authentic Asian food, I liked it very much for its comfort food Asian take-away flavour. Plus, I never managed to get tofu this crips before.
