I agree . I think your dog is being finicky. I say pick the food she ate the MOST. Then stick to that. She'll eventually eat. And make sure you cut out ALL human food.
Just think of it this way...if it was you ..and you had your own personally chef...and you weren't really in the mood for what was being served..but knew something else would come along after it...Yeah you'd be finicky too!!
My husband once told me a story that when he was little..he didnt finish his veggies for dinner. His mom said nothing. Excused him from the table. And then the next morning when he got up...she served him the veggies for breakfast.
