The only beef I have with this so-called sandwich is that I simply do not accept the use of the term 'sandwich' unless it refers to a culinary offering containing a filling which rests between 2 slices of a bread product. Therefore, an 'open-faced sandwich' is a misnomer as is this KFC chicken contraption. This 'sandwich' is simply better eaten with a knife and fork, providing none of the simplicity and purity of a true sandwich.
The Paula Dean Burger loosely qualifies as a sandwich, however, the primary point of using bread product is to protect the eater's hands from the mess of the filling -- while providing a convenient method for consumption. The Dean Burger provides a bread-like covering (doughnuts) but is messy and sticky, providing none of the essential hand protection. I would very reluctantly refer to it as a sandwich.
