Are there good ways to get a depressed girl to eat?

Treat depression: The best way to improve appetite loss caused by depression is to treat depression aggressively with medication and psychotherapy, rule out any medical problems or any other coexisting psychiatric issues.

Appetite/ eating sxs: Dr awan is right on target. Her failure to eat in this situation is likely a sx of depression. It is important to treat the disorder but in this case also the sx. If the girl fails to take in enough calories w significant drop in weight, this could work physiologically to keep her depressed. I don't know her age but if she is a child or a young teen, would recommend seeing a child psychiatrist.
