9 of the most delicious fast-food mashups ever created

• Fast food restaurants are always trying to outdo each other with ridiculous menu items.
• Sometimes that means a mashup of foods that shouldn't quite work together but somehow do.
• Pizza fries, cheeseburger burritos, and donut sandwiches are just a few examples.

We all get in food ruts sometimes. It's easy to get stuck thinking one food just goes with another, and that's all there is to it. But then a fast food mashup will come along and change that way of thinking.

A mashup is essentially combining two foods that don't normally go together, or at least not in the way you'd think, and making a new, weird, and usually delicious food. This is especially common with fast food restaurants who depend on creative menu items to beat their competition.

Sometimes these mashups come from the restaurant itself, like Taco Bell's Waffle Taco or Burger King's rejected McWhopper. And other times it comes from the ingenuity of internet users.

There are countless combinations to be had. Here are 9 of the most delicious fast food mashups ever created that we wish we had thought of first.

Burger King's Whopperito

The Whopperito was, you guessed it, a Whopper in burrito form. Burger King used typical Whopper toppings like lettuce, onion, and pickles, but added queso to give it more of a burrito taste. The Whopperito may have been short-lived, but some fans are still holding out hope for its return.

Carl’s Jr.'s Pepperoni Pizza Fries

With all the possibilities for loaded fries, someone was bound to come up with pizza fries. And thankfully, Carl's Jr was that someone. Topped with pepperoni, pizza sauce, and mozzarella cheese, they joined a long list of bizarrely delicious menu items from Carl's Jr.

Denny's Mozzarella Stick Grilled Cheese

The only thing that can make cheese better is adding more cheese to it. It was in that spirit that Denny’s created the Fried Cheese Melt, which is a grilled cheese with fried mozzarella sticks in it. The item was discontinued, but whip up a grilled cheese and mozzarella sticks, and it should be pretty easy to create your own.
