Maybe you could get one that adds to the one she already has? I've seen grills and small kitchens with the refrigerator, you could just get one of those and add on to it?
If I were to buy my kids a new one, I'd get the Little Tikes Grillin Grand Kitchen.

We have the smaller version of this, the kids like it a lot...I just wish it were bigger now.
