Are you interested in sustainable business practices? You might find this new book by Zingerman's co-founding partner Ari Weinzweig, an interesting read. During my days as an undergrad at the U of Michigan, I sampled many of Zing's tasty treats. Over the last 30 years, the small Jewish deli has turned into an impressive instution with a bakery, creamery, roastery, restaurant and a candy store that supports local farmers, values good food and practices sustainability.
