Cooking Guide: Can't Decide What to Eat?, known in North America as Personal Trainer: Cooking and in Japan as Sekai no Gohan: Shaberu! DS Oryōri Navi (世界のごはん しゃべる！DSお料理ナビ, lit. Cooking Guide: Speak! DS Cooking Navigator), is a digital cookbook for the Nintendo DS. The original, Japanese-language edition was released in Japan on December 4, 2008, in Europe in English on June 20, 2008, in Australia on July 3, 2008, and in North America on November 24, 2008.Cooking Guide is part of both Nintendo's Touch! Generations brand and a cooking tutorial software series started from a Japan-only title, Shaberu! DS Oryōri Navi. In North America, it is also part of the Personal Trainer series.

Cooking Guide is an "interactive cooking aid" that gives step by step instructions on how to cook from a range of 245 dishes. The user is guided through the preparation and cooking process via audio narration and instructional video clips, and the user can use the Nintendo DS's voice recognition to proceed through each cooking step. Users can also choose recipes based on how many calories they have, or what ingredients the user currently has at hand, among other options. Cooking Guide also keeps in memory what dishes the player has already made. The application also allows users to take notes and compile a shopping list, and features functions such as a cooking timer and a quantity calculator. As a bonus, the Game & Watch game Chef can also be played after the user unlocks it by using the timer during preparation of a recipe like in one of its predecessors Shaberu! DS Oryōri Navi. They guide the users in either English, French, Italian, German or Spanish.

Released in Japan in 2006, Cooking Guide was originally shown to the US during Nintendo's Media Briefing at the Hollywood Kodak Theater at E3 2008. It was later shown at the Nintendo US Press Conference Live Blog in San Francisco in October 2008. After selling 600,000 units total in North America and Europe during its first two days of sales, Nintendo announced on April 27, 2009 that the game would be packaged with the latest color to be added to the DS Lite's hardware rainbow which is green. The Green-colored version of the DS lite was released on May 3, 2009.
