What is it?

Two slices of griddled sourdough frame sausage, bacon, a fried egg, and American cheese in this breakfast sandwich from Jack in the Box. The bread gets toasted on the flat top, so the outside turns a little crisp while the inside stays soft and chewy. Compared with the chain’s croissant or biscuit sandwiches, this one leans on tangier bread and a double-meat filling. It’s the breakfast cousin to the brand’s Sourdough Jack, using the same sourdough idea in a morning format. Available during breakfast hours.
