Surely you jest.
Watch your back, tortillas — you have some serious competition in the form of flatbread.(from the Express-News)
Known the world over in many forms — naan, foccacia, saj, pita, chapatti — flatbreads or unleavened breads are staples in Middle Eastern, Italian and Indian cuisines.
All of those breads are nice, and there may be quite a few places in town that feature these delectable delights, but posing "serious competition" to tortillas? Really? Tortillas are king in this town, and they always will be.
I'm going to make a bold prediction here: Never will you ever see a co-worker come into your office or workplace carrying a bag of tacos made with beans and cheese and foccacia. And, if you do see this, something is wrong with your co-worker. Stay away from him. And don't accept his carne guisada on naan either.
