Cube Rule

A standard of determining types of food dishes based on how the starch component of the meal physically relates to the rest of the ingredients. The Rule is expressed using the planes of a cube to illustrate. A single plane is toast. The top and bottom planes denote a sandwich. Three planes forming a trough illustrate a taco. Four planes forming a square tube are considered sushi. Five planes leaving only one open is a meal served in a bread bowl. All planes filled with starch components is a calzone.

I just realized that according to the Cube Rule, a hot dog is a taco.
