I subscribe to the fringe "four foods theory":

1) Substance - Indivisible, elemental food. Example: Vanilla ice cream, no toppings

2) Pizza - Monobreadular, arranged. Example: Nigiri sushi

3) Sandwich - Multibreadular, arranged. Example: Big Mac

4) Salad - Separable, not arranged. Example: Salad with croutons

What is lasagna? It doesn't seem to easily fit in any of those categories, although it's clearly not a "substance".

Sandwich, as it is multibreadular and arranged.
