If you’re on of the many people looking to live a little bit more sustainably, look no further than that 11th annual Boston Local Food Festival, which returns to the Rose Kennedy Greenway September 17 from 11 a.m.–5 p.m. Sample healthy food grown and produced all over New England—including fruits, vegetables, seafood and artisan specialties like cheese, hot sauce and granola—at this free happening. Billed as the region’s biggest one-day farmers market, this grand cornucopia also features live music, cooking demonstrations, kids activities in the Family Fun Zone and Hub chefs battling for supremacy in the Seafood Throwdown. The local vibe extends to the beverage selection, as visitors can sample wines and craft beer from local producers. There are even food-inspired arts and crafts on hand, so bring your reusable shopping bag and load up on all kinds of goodness from Boston and beyond at this zero-waste event.
