If I have a hard shell taco that splits, it has become a sandwich according to the cube rule of food identification.
The author has toast (1) as an example of a sandwich (2) for goodness sake.
My criticism is that they don't address non-surface-defined foods, aside from their total non-commitment on rice.
Edit: my bad, foods with no containing surfaces are considered salads.
