She is really lucky to have people around her that care so much - I had GD so pretty much lived on eggs and tuna with heaps of veges - but sounds like you have a bit more of a challenge on your hands. The dietician I saw was a big fan of beans!!! Some other snacks I used were Diet yoghurt, nuts (almonds especially) and peanut butter or cheese on 9 grain vitaweets. But a bit of a change from vanilla slices....We also made homemade pizzas on pita bread as a quickie also!

Good luck
