Engadget shares this nugget:
Plant-based meat substitutes may soon be an option for fast food chicken. CNBC reports that KFC will start testing Beyond Fried Chicken at an Atlanta restaurant on August 27th. Yes, you could grab a bucket of chicken without feeling quite so guilty — or greasy, if Beyond Meat's earlier work is any indication. Whether or not availability grows will depend on feedback, but other restaurant chains (such as Del Taco) have seen upticks in demand since adding meat substitutes.
KFC had acknowledged talking to suppliers months ago to investigate meatless chicken, but didn't have any definitive plans until now.
