Alternate dashi methods

I often find that I just can't be bothered to take out a pan to make dashi for a single, small bowl of something that only I'll be eating. So, I've been pondering some alternatives. With a large water dispenser which produces water hot enough to leave quite a painful burning sensation and red mark throughout the day and night and a microwave and rice cooker (with one of those switches without any actual settings) at my disposal, I feel there must be some way to make small portions of dashi without the stove.

Help! Cooking in a microwave rice cooker!

My sister is traveling and has no stove or hot plate, so a microwave is her main way of cooking. She bought a microwave rice cooker similar to this one http://www.amazon.com/Maxi-Aids-Microwave-Rice-Cooker/dp/B00011R41Q?tag=dogpile-20 that was also advertised as making pasta, but her husband threw away all the packaging and instructions. I need any instructions for cooking rice and pasta in a microwave rice cooker. Please help. Thank you.
