100-Mile Dieter Alisa Smith, co-author of Plenty, spreads the gospel of local eating Monday at Fox & Obel (scroll down). Sponsored by Slow Food Chicago, Smith’s talk should serve as a good primer for anyone planning to throw down with the Green City Market‘s upcoming Localvore Challenge, slated for September 10-16. It’s unclear to me exactly what the “challenge” entails, at least as a collective endeavor, beyond a (so far pretty sleepy) discussion board. Are there prizes? Mixers? Recipe swaps? If I get out of bed in time I’ll be going to the market tomorrow to try and find out; you can sign up there for the challenge Wednesdays and Saturdays through September 9.
