Today Subway has announced that, beginning next Monday, it will offer flatbread as an option for any of its existing sandwiches, and will also introduce two new sandwiches, Chicken Florentine and a Steak & Bacon Melt, made with flatbread.

In a departure from Subway's signature fresh-baked bread philosophy, the flatbread dough will be baked off premises, then supplied to Subway franchises and finished off in on-site ovens.

With this launch, Subway is attempting to make headway in a tight market that includes other chains such as Dunkin' Donuts and Quiznos, which both already carry flatbread sandwiches. Do you think Subway's new product will take off?
