I've been eating out a lot. I'm on vacation in Florida for the winter and having friends and family come and go. Recently we went to The Hurricane Restaurant in St. Pete Beach and they wasn't much on the menu for a dieter.
I ordered a Turkey Cheese on Cuban Bread, NO butter, NO mayonnaise, MUSTARD ON THE SIDE. I ate the filling with knife & fork & mustard and ate 1/4 of the bread spread with mustard. But I'm a mustard lover. Result: no weight gain that day!
