evidence: Two chicken patties, special sauce, lettuce, cheese, pickles on a sesame seed bun – no onions, but wait, chicken? Yes, the Chicken Big Mac is coming to McDonald's starting Oct. 10. A special Big Mac is about to hit McDonald's menu – and it's not the return of the Double Big Mac from earlier this year. [...] "With the introduction of the Chicken Big Mac, we’re excited to pay homage to one of our most iconic menu items, the Big Mac, and introduce it to a whole new generation of fans," said Tariq Hassan, chief marketing and customer experience officer at McDonald’s USA, in a press release. "By tapping into some of our fans’ biggest passions from dupe culture to live-streaming, we’re able to serve up more than just a sandwich. There truly is something for everyone to enjoy in this campaign and we’re bringing experiences that will surprise and delight them, all before the Chicken Big Mac hits restaurants."
