If you miss sandwiches made with bread, tortillas are the answer. Their dough is unleavened so your intestinal tract digests them more slowly than bread. They are one of the few wheat or corn flour products you can enjoy without giving yourself a glucose shock. To make a "wrap," just wrap a tortilla around a generous portion of sandwich makings, fold one end so the ingredients don't fall out, and gobble it up. A sandwich made with two slices of bread has a glycemic load of 260, while a wrap made with a wheat flour tortilla has a glycemic load of about 80. The glycemic load of a whole-wheat tortilla is about half that.
