Each year, The Observer does a tournament, timed with NCAA basketball's March Madness, that focuses on one area dish. This year, we’re trying something new.

Here's how to comment, if you never have: Scroll to bottom of this particular post and click on the "119 COMMENTS" phrase. (Number may be different.) Then click on "Jump to Comment Form." Type your comment into the empty box, then click on Name/URL and enter your name or a screen name (like a pen name). Then hit "Publish your comment."

The category is sandwiches. But because so many restaurants offer so many sandwiches, and because I suspect readers know about some great ones I will never find, we’ll have readers “vote in” eight specific sandwiches from specific restaurants -- by commenting on this blog post by 5 p.m. March 7. For example, a reader might vote for the Darby’s Roast Beef Deluxe at the Common Market. You must name both the specific sandwich and the restaurant to have your vote counted. (PLEASE read the rest of the rules below before commenting!)

The eight specific sandwiches that get the most votes will be in the tournament. I’ll also choose the four most intriguing sandwiches suggested by voters – meaning that if there’s a sandwich that sounds terrific from the voter’s prose, but no one else seems to know about it, it can still make the tournament.

I’ll name an additional four of my own choices to round out our starting bracket of 16.

Other rules: No burgers. (That was last year.) No barbecue. (That’s in the future). No chains with locations outside the Carolinas.

And no anonymous comments will be counted. You have to have a screen name – which, as a reminder, doesn’t have to be your given name; this just allows us to count one vote per commenter.

After that, it’ll work as usual: I’ll create the pairings and publish the bracket March 9. Then readers will vote on pairings, and both those results and taste tests will be used to determine which sandwich advances.

We’ll announce the winner March 30.

Let the games begin. (Also: Folks who have Liked my Facebook page or follow me on Twitter @helenschwab got a head start on this. You can stay in the loop by Liking www.facebook.com/hsondining.
