Subway's Footlong Cookie

The sheer size—12 inches long and 1 inch thick—means you're consuming 30% more calories than a typical fast food chocolate chip cookie order from rivals like McDonald's. Unlike the Jack in the Box Tiny Tacos, which at least offer savory contrast, this cookie is a one-note assault of excessive sweetness. It costs $3.49, making it 20% pricier per calorie than Subway's own sandwiches, a stark reminder of how the chain's health halo is betrayed by its worst menu offering.
