Everything sandwich
Somehow, every time I make myself a sandwich an everything bagel comes to my mind. I didn't know exactly what it was so I finally had to look it up. Contrary to the name it doesn't actually contain everything. It doesn't even refer to fillings of a bagel. Instead it's just about the toppings, mostly a certain combination of them. But usually any multi-topping bagel can be an everything bagel. So it doesn't even have everything as a topping.
