I will venture to say that even one piece of bread suffices, as in "open-faced sandwich."
Does that mean a single slice of toast with butter on top is a sandwich?
That depends on how much butter we're talking. If it's a small amount of butter then it's just a condiment, but if we're talking about a half stick or more, I suppose that could constitute an open faced butter sandwich.
Except that open face sandwiches aren't real sandwiches.
Also, if the butter is thoroughly soaked into the bread, then you've got buttered toast. Buttered toast makes good BLT sandwiches.
Open faced sandwiches are for cheapskates. WTF does the extra slice of bread cost? Is your atention span so short that you can't finish making it a real sandwich?
Just seeing "Open Faced' reads like an apology on the menu. Sorry sir, our cooks are too lazy to make a sandwich, have this abomination instead that you can't possibly pick up and consume the way a sandwich is meant to be eaten. Please enjoy our half assed cooking; sincerely, Management.
P.S. ANY F**Kin sandwich that requires utensils is not a sandwich! Rot in the after life you cursed abominations.
You are wrong here. An open faced sandwich means there's twice the amount of goodness stacked on each separate piece of bread. Would I rather order a crab sandwich or an open faced crab sandwich? One way might yield me twice the amount of crab.
Pick it up and eat it while wearing an expensive shirt. If it makes you nervous, then its not a sandwich. You should be able to play cards while eating it, as the good Earl intended.
A sandwich is defined by its simplicity to eat. If its not simple, its not a sandwich. Once you require utensils or dishes you've screwed up.
Clearly you don't understand the topping to bread ratio. If you find that you need more filling to bread, then put more filling in between the two slices of bread. If you enjoy eating crab filling, feel free to eat a giant pile of filling. But for f$*ks sake, don't mess with an already perfect food.
What you described is crab toast or crab on bread, even millenials are smart enough to understand the concept; ever hear of Avocado Toast? Millenials who spend all their money* and can't buy houses are still smart enough to understand that its not an avocado sandwich.
*see wall of shame, apparently all millenials are broke because of avocado toast. There are no millenials apparently immune to this, but they all still know they're not buying sandwiches.
