Step 1 : Introduction to the question "Which fast food chain introduced the Baconator in 2007?"
The Baconator is a sandwich sold by the fast food chain Wendy's. Wendy's describes the Baconator as a "tasty treat" made up of two beef patties, two slices of American cheese, six strips of smoked bacon, mayonnaise, and ketchup on a bun. The Baconator was introduced in April 2007 as part of a "back to basics" reorganization by Wendy's new CEO Kerri Anderson. The Baconator is available as a single, double or triple, depending on how many beef patties and bacon slices it contains. A Baconator single has 610 calories; a Baconator double has 980 calories; and a Baconator triple has 1,150 calories.
