As August kicks off and our usual crop of late-summer convocations is readied for harvest (see below), one new plant-based event especially stands out: S.E.E.D: Sustainable Everyday Edibles and Drinkables will be held from 2 to 6 p.m. Aug. 14 at SugarHouse Casino. It will showcase vegan foods from Rachel Klein, Vegan Chef Lenka, MomPops, the Soy Cafe, and Sweet Freedom Bakery, among others. And you can wash all those goodies down with a vegan beer from one of 18 participating breweries large and small, ranging from Sam Adams to Weyerbacher Brewing to Neshaminy Creek Brewing Co.
