In this whimsical story, Grandad is convinced that almost every dish is “missing something”—usually the secret ingredient that makes everything better: tomato sauce. Through a series of hilarious kitchen mishaps and family adventures, we follow our 7-year-old protagonist as she embarks on a mission to solve the mystery of Grandad’s picky palate.

Is it a lack of seasoning? A texture issue? Or does Grandad just need a little extra dash of “detective-approved” tomato sauce to make the meal complete?

This title turns the recurring tomato sauce bottle into a central character/plot device, creating a fun, interactive reading experience. It frames the “fussy eater” conflict as an exciting investigative adventure, making the story feel less like a lecture on eating and more like a high-stakes, family-filled caper that children will love to follow.
