Phillip Foss' ever-evolving business plan for his Meatyballs Mobile now includes this: the opportunity for you, the eater, to create your own edible spherical treat with Foss' help and then ride along for a day to sell your creation.
Foss explains this on his newest site, phillipfoss.net (one we can actually access; our Web filters for reasons yet unknown have declared Foss' Pickled Tongue blog "malicious." Is it the "tongue"? The "balls"? Who knows.).
First up, from 11 a.m. to 1 p.m. today, at Monroe and Wells: one Brian Eng, who writes the blog Chow-Eng Down and appears to be your typical camera-happy foodie, and his Banh Mi-tyballs ($8).
Foss will be auctioning off another create-and-ride-along at tonight's Meals on Wheels event at Macy's on State Street. Tickets at the door are $125.
Sun-Times Food editor Janet Rausa Fuller is always thinking about her next meal.

And why should they?
Food keeps evolving, but apparently ball jokes never will.
