I agree with some of the others - just give her what you are eating for dinner - she is old enough to eat anything you eat, and it may be more appealing, since it is "what the grown-ups are eating". Plus you don't want her ot get used to having a special meal made just for her, and expect it forever....unfortunatly lots of people I know have fallen into that trap and are now making 3-4 separate dinners for their school-age kids....that is rediculous.
As they get bigger, their growth rate slows a bit form those first 2 years, and their appetite may decrease some. Just offer her what you have for dinner, and let her eat what she wants, and leave it at that, if you get to frantic and start begging/tempting/bribing her to eat, it WILL be come a power struggle - a nd you don't want that.
Good Luck
