Subway says it will start making its sandwiches healthier and bigger.
Subway came under fire two years ago when a photo went viral online showing a foot-long sub next to a tape measure that showed the bun was actually 11 inches.
The photo prompted a lawsuit from customers who said they were cheated out of an inch of their sandwiches.
Subway has now agreed to start requiring franchisees to measure the bread to ensure that foot-long subs are 12 inches and 6 inch subs are no less than 6 inches.
Subway said Tuesday that it plans to switch to meat raised without antibiotics over the next several years.
The announcement comes after the company was targeted by advocacy groups calling for the change, with a coalition planning to deliver petitions to Subway's headquarters on Thursday.
