If you’ve got a great recipe for a traditional Mexican dish, you’d better hurry: the deadline for submissions to the “Recetas de mi tierra” cookbook contest is this Friday. The National Museum of Mexican Art is holding the contest to celebrate its 20th anniversary, and winners will receive a copy of the cookbook, not to mention “their place in history.” Contest guidelines can be found on the museum’s Web site. 

Chicago’s inaugural Pizza Fest kicks off Saturday at noon on the 2300 block of N. Racine and continues until 10 PM –Sunday it starts at the same time but ends at 8 PM.
