By sandwich, I am excluding "the Shaggy", where you just pile every good thing you can think of on.

I mean what is your favorite traditional sandwich, such that you could say the name to a stranger and have a reasonable chance of them knowing what fillings you are thinking of.

You may include candidates which are not not universally be considered a sandwich, such as hot dogs, quesadillas, burgers, etc. So long as you genuinely beleive it to be superior to all other sandwich forms.

My current shortlist of candidates, as examples:

1. Grilled Cheese - Simple, easy, accessible to the masses

2. Bahn Mi - A Vietnamese sandwich of a split baguette with kewpie mayo spread, stuffed with marinated grilled pork, cucumber, carrot, and sliced green pepper.

3. Italian Combo - An informal sub combination typically consisting of salami, capicolla, and some form of cheese, mozzarella being used as a default .

You can choose your own metric for what makes for a superior sandwich and may consider any standard toppings for the sandwich like mustard/mayo to be included.
