Wendy's offers an interesting, if questionable, trio of heat with sweet Thai chili sauce, green chile cream cheese, and chipotle mayo. Also part of the sandwich is a crispy fried chicken breast fillet, spring mix, and crinkle-cut dill pickles on a brioche bun.
I'm not sure how the sweet, tangy spiciness of the Thai chili sauce squares with the creamy, tangy spiciness of the cream cheese and the smoky, creaminess of the mayo. Sounds like it could be too busy or just really weird. Usually, you just go with one or the other but I suppose that's why it's in test.
The green chili cream cheese in particular is something that hasn't been done by a major burger chain.
