Hey Max, join the club, lol. My son was the same way for years, we kept asking his doctor how to get him to eat, his answer was always, "he'll eat when he's hungry". Now hes 14 and I can't buy enough groceries, so give it some time, she will eat when she's hungry.
My daughter on the other hand was a natural eater, and she like good food like veggies and fruit. She has never changed and shes 18, her favorite snack is sliced tomatoes with salt and pepper, so it all depends on the child.
I know that answer doesn't help much, but that's how it is. Time changes everything, so just keep testing different foods until you find something she likes :)
