I would argue that the use of 'sandwich' in the name "ice cream sandwich" is more adjective than it is noun. The word is being used to help describe the object, rather than define it.The above cited sandwiches are, by their very name, sandwiches and all would fit firmly in the "Lawful Good" slot.
If we were to show an ice cream sandwich to someone and ask them at a base level what it was... they'd say it was ice cream. Ice cream in a weird presentation, but ice cream nonetheless. The 'sandwich' part is just using an analogy to help us understand what the ice cream is shaped and appears like, not that it is one.
