As a rule, I don't make her eat (or even try) anything she doesn't want to. She eats a wide variety of foods to begin with, and knowing her personality, if I turned it into a power struggle, she would eat way fewer things. We make this green bean stew that we sprinkle feta cheese on at the end, and she liked the stew but not the cheese, so she now shouts "no feta cheese!" whenever we mention feta cheese. Except she has eaten feta in several other dishes without complaint before and since. We just don't mention the name.
