In honor of our new cookbook, Lighten Up, America! we want to see your favorite regional dish. Here's your assignment: Take a photo of your favorite regional dish, write a short caption about why it is your favorite, and upload here. You also can submit on Twitter or Instagram using the #LightenUpAmerica hashtag.

10 semi-finalists will receive a copy of Lighten Up, America!. And one Grand Prize winner will receive a $500 gift card and have their dish lightened up by author Allison Fishman Task.
