Can We Have A Treat?

Isabelle and Joe love to eat treats, but they are picky eaters and scared of new foods. When given hummus for dinner, they say they don't like it before even trying it. When given sausage for breakfast, they say the same thing. Will they be adventurous enough to try new foods? Will they be surprised to find that they like the new foods? And will they learn that, sometimes, eating new foods is better than treats?
