If you were to create the world's greatest sandwich, what would be the ingredients?

That's already been created and it's called the Schmitter Sandwich.

The iconic sandwich was named after Schmidts Beer and served only at McNally's Tavern and at Philly sports arenas. Steak, salami, onions, tomatoes all fried together, served on a Kaiser roll slathered with special sauce.

I don't think I've ever had a better sandwich in my life and can't go to a Phillies or Eagles game without having one.

Spam, eggs, baked beans and spam, with a spam topping.

I agree with Hippy, it already exists. Blackened Grouper with red onion slaw, pickles, tomato, a slice of prosciutto and pepperjack cheese on a Kaiser roll.

Mmmm-mmm. 👌

Sandwiches aren't hard to get right for me. All I need:

Toasted sourdough, dijon mustard, salami, red onions, bell peppers, pepperoncini, some salt, pepper, and lettuce. Simple, but perfect. No cheese please :D

I have a few, this is mine at this time. It will change come fall.

Fresh whole wheat bread, spread with whipped cream cheese, thinly sliced smoked turkey, thin cucumber, sprouts, and avocado. Piled so high that you have to smoosh it down. A bag of chips and a bottle of ginger beer. Done.
