My kids drive me nuts sometimes. Usually it's around the dinner hour. Inevitably, I make something that one of them doesn't like. It's usually Missy - she pretends to be a fairly picky eater. Sunday night I made turkey ala king - the standard post-Thanksgiving meal that is Buddy's FAVORITE meal of the year - he'd prefer to have turkey ala king over the whole Thanksgiving dinner. Of course Missy turned her nose up at it. "I don't like that." "Have you ever tried it?" "I'm sure I have." "Well, I'd like you to take a bite to see - there's nothing in it that you don't care for." Of course one bite was enough for her.
Occasionally the one bite thing works - she said she didn't like the Schwan's beef goulash that I made a few months ago. I told her she needed to try some anyway and it turned out to be one of her favorite dishes (for that day anyway!). I'm sure the next time I make it she won't like it again.
Don't get me wrong - I've told the kids thousands of times that I am not a short-order cook. If they don't like what I've made for dinner, they are welcome to make their own meal (and clean up after themselves), but I won't make a separate meal for them. On turkey ala king night, Missy helped herself to an apple, yogurt, and a tortilla with melted cheese inside (that was probably healthier than the turkey ala king anyway!). Sometimes she'll have a bowl of cereal or toast.
Buddy will generally eat whatever I make, but occasionally he'll get an attitude and just decide not to eat at all - maybe because the meal wasn't finished yet when he decided it was time to eat, or he got mad at me for something else, etc. It's more of an emotional battle with him than it is him not caring for the type of food. I don't let that bother me either though - if he doesn't want to eat, that's fine - there will be another meal in a few hours (or tomorrow morning). He's not going to starve to death.
If my kids had their choice, they would probably have Chipotle or Subway for dinner every single night.
