Is she not eating it because she thinks it is bad for her, or not eating it because she doesn't want it....it doesn't taste good or even sound good. That's different.
If it's because she thinks it's not good for her, you can try things like veggie casseroles, and squash soups, and cheese.
If its a taste thing, there are appetite stimulants.
Just a few thoughts.
I know that you are trying everything you can. Keep plugging!
