If you take it from the perspective that a child will likely take it, I'm probably reading too much into it. A child will look at it and think, "Oh, there's a lot of food I don't like, and my parents sometimes resort to ridiculous lengths in order to get me to eat food that I claim to not like, and it sometimes turns out that I like it," so I think they'll identify with that. I guess the important part is that the main character does like it.

Try new foods. Or, if you keep annoying somebody enough, they'll give in to what you're asking for.
