I had a quiznos flatbread sub today, "Traditional" with no dressing and double meat. It was a LOT of food-- I certainly wouldn't call it small! It was fantastic.

I don't know all the nutritional info, just the "net carb" count, and I have no idea if any sugar alcohols are involved. The flatbread wasn't great, but it tasted like wheat and it held the food together. Of course, there's also no way of knowing how much sugar is used in processing the deli meats, or if one kind of deli meat is not as bad as another kind. In any case, it works if you have no food with you, no way to get home to cook.
