An instant New York Times bestseller From Netflix star and New York Times bestselling author Phil Rosenthal and his daughter Lily comes a hilarious picture book about a food-loving dad encouraging his picky eater daughter to just try something new.

Phil has one rule about food: try everything at least once. Otherwise, how will you know what you like? His daughter Lil disagrees. She already knows what she likes--just bread and pasta with no sauce--and that's all there is to it!

When the two go to a food truck festival, Phil tries introducing Lil to all kinds of delicious cuisine, but she doesn't budge. Just when it looks like it's going to be a very long day, an unexpected mustard accident changes everything.
