Street food is fast gaining green cred. (Call it organic meals on wheels.) Not only are vendors plying more sustainable delicacies, but their trucks and carts are running more efficiently, too.
Take Liba Falafel Truck, which takes to the streets of the San Francisco Bay area daily with a load of organic and locally grown Middle Eastern chow in a biodiesel-powered truck that uses converted vegetable oil from the kitchen.
Likewise, Los-Angeles-based Green Truck serves gourmet organic street treats (follow along on their Twitter, Green_Truck, for locations) from its cooking oil-fueled trucks. Plus, its kitchen is solar-powered and all containers are biodegradable.
