A club sandwich used three slices of toasted bread and two layers different fillings?

That's right! A classic club sandwich typically has:

* Three slices of toasted bread: This makes it a "triple-decker" sandwich.

* Two layers of different fillings: These can be anything you like, but common ingredients include:

* Meat: Turkey, ham, bacon, roast beef

* Cheese: American, cheddar, Swiss

* Other: Lettuce, tomato, mayonnaise, avocado, pickles

The fillings are usually stacked in a way where you have one layer of filling on the bottom slice of bread, then a second slice of bread, then the second layer of filling, and finally the top slice of bread.
