On the May 16, 2006 episode, Ze challenged his viewers to create an "Earth Sandwich." The goal was to place two pieces of bread on the ground at points directly opposite each other on the globe, creating a giant sandwich between the two pieces of bread.[9] The task was completed by brothers Duncan and Jon Rawlinson in Spain and Morgan in New Zealand.

You mean like that ?

"Open faced" sandwiches. Avocado toast is a sandwich.

a stack of pancakes or waffles is a sandwich that many are too dainty and proper to eat with their hands.

when you grab more than one French fry, that's a sandwich. and the condiment you dip it in is like the au jus.

lasagna is an oven baked sandwich. same with multi layer bean dip.

conceptually, a sandwich is a edible delivery system for helping you eat with your hands. a bread bowl is a sandwich.

I used to do a temporal sandwich where I'd eat a slice of bread, other stuff, and then another slice of bread. I can't seem to place what the middle was. It may have been goldfish crackers.

A western sandwich is bread, (vegan) meat or cheese, sauce, tomato, something pickled, some salad

Observe:

• bread - wheat raised with yeast and left to rise

• meat - probably smoked or salt-cured or something

• cheese - milk, coagulated and aged

• something pickled - a vegetable was left in an acidic brine

• sauce - perhaps it is a fermented sauce

A pattern emerges:

• something edible was preserved through a biological process and left to develop flavor

From here we can see that the ur-sandwich is not about structure or ingredients, but rather the number of different preservation processes brought together into a single dish.

Stuffed peppers

The comically large sandwiches like Shaggy eats on Scooby Doo.

A burger is a sandwich.

A meatball sub however is not a sandwich.

I guess a samosa is kind of a sandwich.

A classic from college:

• Ellio's pizza, cooked according to directions
• Doritos, crumbled
• Stack, fold, or wrap, according to taste/hand-eye coordination

Thus, the sandwich is Western in form (bread/sauce/cheese/other/cheese/sauce/bread), but the layers cohere to produce an irreducible whole apart from its components. The sandwich has the portability required for every occasion from the boardroom to the discotheque while maintaining a utilitarian, even proletarian, character. And it contains enough preservatives that if you made 1000 of them today you'd survive through Judgment Day.

I actually do this one, mix of peppers, onions, different mushrooms maybe, garlic and olives fried up and then use 2 toasted (on a pan not in a toaster) portobello mushrooms. I've also done the mushroom for bread with a leftover red cabbage and carrot vinaigrette coleslaw, vegan Russian dressing, saeurkraut and tempeh and it was a sorta reuben. Fucking amazing.

When I did morning shifts at my previous job I would often eat what I would call The Bananarito, I'd make a large thin pancake and wrap it around a banana with nuts, whatever fruit was around at the time and this amazing date caramel sauce we had. Wrap it up, pop it in a press for a bit. I'm not a breakfast person and generally all I can stand to eat for the first bit after waking up is bread, fruit and nuts. You can add a bit of oatmeal in there too.

Jibarito is Western style but uses a plantain instead of bread

Edit: ok I see what you're looking for now. I'm sorry you're limited to three spatial dimensions

Tortas, imagine a burrito but with sliced bread and not a wrap.

Paninis are the grilled cheese’s classy older sibling. But some balsamic-portobello mushrooms, tomatoes, basil and a vegan cheese in a sandwich with ciabatta bread, grill it and serve.

I want to try a vegan croque monsieur recipe (ham and cheese but ), but I need to find a good recipe.

Onigiri, assuming it's stuffed with something. Comes with its own edible wrapper and everything.

I'm currently eating them on long bike rides to hit my carbs and it's working pretty well.

A gordita/pupusas/arepas are tecnically a sandwich if they have more than one layer

From my general region... the open-faced sandwich!

Look up "horseshoe" and despair.
