Lay's mystery potato chip flavors revealed

For the third year running, Lay's is out with its newest batch of fan-nominated flavors.

The potato chip company chose four finalists from millions of fan flavor submissions.

Last year's winner was Wasabi Ginger.

This year's new flavors are Wavy West Coast Truffle Fries, Southern Biscuits and Gravy, New York Reuben and Kettle Cooked Greektown Gyro.

The flavors will be on shelves July 27 through October 18.

Consumers can taste and vote for their favorite once a day at DoUsAFlavor.com or via hashtag on Twitter and Instagram.

The winning flavor will be revealed this October and stay on store shelves longer than the other three.
