Hi and welcome to YT - glad you posted
!
I wonder...especially since she seems to like fresher foods (apples, carrots, sweet potato, watermelon)...if you should try something like the cooked (they have raw too, which is what I use) Sojos mix.
THIS PAGE shows both the raw pre-mix and the cooked pre-mix. All you'd have to do is add your own meat (raw or cooked). It's somewhat similar to Honest Kitchen food, if you've heard of that already...? HK would be another option, btw.
My gut feeling is that she'd do better on fresher foods...even a canned food, perhaps. Have you tried that yet?
Have you tried sprinkling Parmesan cheese on her food yet...?
Keep us posted and best of luck
