That's easy, I don't really give them a choice. I'm one of those mean old moms that just MAKES them at least TRY new stuff. And I don't cook for 5 different people. I cook for the family. If I fix dinner and you don't like it, then YOU can fix a peanut butter sandwich or Ramen noodles. Now keep in mind, I don't cook things that I KNOW they don't or won't like. If I try new things, it's always something that I know they'll like. So if they DON'T, mainly because they're just being incorrigible, then they can fix something for themselves. It's as simple as that.
