Alone in China for 1 month with just a steamer- meal ideas?

Looking for ideas for things I can make with just my electric steamer (and the bottom part which doubles as a pot.. I think?), ideally meals that are relatively healthy/fulfill nutrition needs at the least. Since I’m alone and not going to be here that long I don’t want to buy too much of any one thing or buy new appliances. I’m walking distance away from a couple supermarkets so I can buy precooked meats and some frozen foods.

I’m not very experienced so help would be very much appreciated, thanks in advance!!
