A lot of owners give their hams a dog biscuit, usually bonio biscuits now & then, not all hams like them but many do enjoy them, it makes a nice treat for them & is good for their teeth if they will chew on them, most go mad for whimzees which are also good for teeth other than that I would just stick to hamster food & treats.
I wouldn't worry too much about the quantity of veg, they rarely if ever eat more than they need so you can give a small piece daily, plenty of variety, just check that none gets stashed away anywhere & remove what hasn't been eaten the next day.
I would still keep a close watch on both her weight & water consumption as she does seem to be drinking a lot.
