If you're a fan of the sweet onion chicken teriyaki or oven roast chicken at Subway your not just eating chicken. Researchers tested chicken from McDonalds, Wendy's, and Subway. 85% chicken DNA was found from McDonalds and 90% chicken was found at Wendy's. Chicken at Subway though only contained 50% Chicken DNA. What the other 50% is.... we don't know. You might want to think twice before ordering.
