Hi, I'm Jack (that's a pseudonymn by the way) and I'm a PKUer. (sounds like I'm in AA or something) Chinese sounds fine if you don't overdo it. Stay away from meat it is probably the single most protien laden item she could eat.
On the other hand, I am aware that there are pills one can take which would allow them to eat meat. If it's really that much of a big deal maybe she can get on those. Personally I perfer the diet… but I don't really care for meat anyway… I have other non-pku friends who are more extreme in their self-imposed restrictions than I am.
