Hmmm...some of Zen's advice could be a little dubious if she already knows what your apartment is like, although I'm sure she'd appreciate the sentiment. Do girls really get into 'cute' untidyness? lol
Fresh, I'd recommend someting simple like salad with grilled fish or chicken. Generally for chicks you can't go wrong with that, especially if you're not so great in the kitchen. You can always dress the chicken up with some fancy store bought sauce if you want.
For desert, icecream and fresh fruit with a nice sweet sauce is another simple but tasty option.
For entre, try crusty bread with a simple dip of olive oil and balsamic with salt to dip in...or dukka if you can get it there.
Too easy, and hardly any time in the kitchen.
Oh, airing out the apartment was one of the tips you definitely should try.
