If there’s anyone in this town who knows what to do with seasonal veggies it’s Cassie Green of Green Grocer Chicago. She’s a champion of searching out produce from local farmers to ensure her little shop on Grand is well stocked. And what do you do with that fresh produce? Cassie’s conducting a cooking demo with three recipes at the Kenmore Live Studio (678 N. Wells) on Thursday, May 19, at 7 PM. It’s free.
