Ok ... everyone is familiar with reubens ... and southerners know the grouper reuben which is very good. Well for some, grouper is very expensive and sometimes not always available. So here is my twist. This is a great double decker sandwich, still grilled with all the traditional flavors and a little twist. This sandwich is so big it is great as a main course or just cut in half and served with a side of soup. A creamy potato soup or any favorite would make this dinner.
