Go on vacation for a week, and you miss everything.

Chefs change their names, beloved soul food restaurants take their last breath, food trucks start rolling.

About those trucks -- or the one helmed by Matt Maroni that had everyone waiting with baited breath for. Less than a week in operation, and the Gaztro-Wagon already is welcoming guests.

Today's two-fer: Maroni and Lockwood's Phillip Foss (at right), who will be serving a Tunisian lamb naanwich. (Foss says it's a nod to his wife Keni's own food truck concept in the works. Again, see what happens when you leave town?!)

Maroni says he will be riding with guest chefs for next 10 days, to drum up support for next week's Taste of the Nation event at the Aragon Ballroom. The uber-multitasking Foss will no doubt be drumming up support for his pet cause du jour, Thursday's Speakeasy Throwback at the Palmer House Hilton. The event will benefit former Paramount Room bar manager Shawn Koch who is fighting a rare form of brain cancer.

Follow the wagon on Twitter to find out its whereabouts -- and who else is coming on board. First stop for Foss and Maroni today: the Board of Trade in about a half-hour.
