Families interested in greening up their kitchens and reducing food waste might be interested in a parents-only class at The Kids' Table on Jan. 31. It includes a worm composting demonstration by Urban Worm Girl and "waste-not-want-not cooking demos" by Kids' Table. 

The evening will also feature light food, complimentary tastings of organic/biodynamic wines, a raffle, and sustainable goodie bags. Cost is $10. For more information, call 773-235-2665.
