Chipotle is offering up free burritos – if you’re willing to embrace tofu. If you buy the spicy organic tofu topping Sofritas on Jan. 26, Chipotle will give you a free entrée of any kind. That’s right: buy one, get one free burritos. Simply save your receipt and bring it back to Chipotle to get your free meal any time before Feb. 28. So you know.
