The 15 Most Bizarre Fast-Food Menu Items Of All Time (Slideshow)

Biryani, the popular South Asian rice dish, is about the last thing you'd expect to see at a Pizza Hut, but last July the "Birizza" hit the menus at locations in Sri Lanka. The dish was offered with either chicken or paneer cheese, and was topped with a pizza dough crust (starch on starch!). An onion salad came on the side, as well as spicy gravy. 

In August 2013, Subways in Japan added a new meat to the menu: a long sausage, topped with barbecue sauce. As usual, guests were able to choose the cheese, bread, and veggies. I think we can safely say that we won't be seeing stateside Subways offering sausages any time soon. 

For some reason, cheese-topped donuts are quite popular in Indonesia, and in September 2013 KFC decided to get in on the action, offering a glazed donut topped with shredded Swiss and Cheddar cheese. Here in America, we only eat cheesy donuts if they're sandwiching a burger patty!

A cheeseburger pizza isn't so wild around these parts anymore; it's usually just a regular pizza topped with ground beef and American cheese. But in England (and previously in the Middle East), Pizza Hut released a limited-time only pizza where the crust was actually made out of little cheeseburgers. They were topped with mozzarella, and ketchup was served on the side. 

This offering made international waves last October for its sheer outlandishness: a burger patty, onions, lettuce, mayo, a hash brown patty, and a giant piece of bacon were sandwiched between a black bun. Meant to resemble a ninja with his tongue sticking out (seriously), the burger even had its own mascot. 

Last year, Pizza Hut briefly sold a pizza in the U.S. that was ringed by tiny pizzas (pizza spawn?) along the crust. The Puerto Rican division took it one step further in December by adding a sprinkle of bacon to the top of those tiny pizzas. Touché, Puerto Rico, touché. 

Not to be outdone by the infamous Double Sensation described earlier, Pizza Hut Singapore went even more overboard with their holiday special last December. The bottom pizza had a stuffed crust and was topped with chicken pepperoni and bell peppers, and the smaller pizza stacked on top of it was topped with rolls of turkey ham and Edam cheese, tomatoes, zucchini, and mango mayonnaise. Insanity. 

In December, locations of Domino's Pizza in Australia offered probably their highest-end pizzas ever, made with Wagyu-grade super-marbled beef. The first pizza, the Wagyu 3 Ways, was topped with Wagyu rib meat, Wagyu bresaola, sliced, Wagyu sausage, smoked rasher bacon, ground beef, and tomato-bell pepper sauce. The second came topped with Wagyu rib meat, truffle-infused hollandaise sauce, Camembert cheese, cherry tomatoes, and red onion. The two pizzas were sold together for $50 (about $45 USD), and when you ordered one your order was automatically bumped to the front of the line. 

Mincemeat pies are quite popular in the UK; they used to include actual minced meat along with chopped fruit and spices, but today most varieties forego the meat. As a special holiday treat last year, Krispy Kremes across the Kingdom released a Mince Pie doughnut; no word on whether it included meat, but we're going to just assume it didn't. 

This pizza, which was rolled out in India in December, is beyond cheesy, and that's saying a lot. The crust was not only stuffed with jalapeno cheese, it was topped with a cream cheese-based sauce instead of marinara sauce as well as mozzarella cheese. Cheese on cheese on cheese on bread? Yikes. 

This here's an interesting one, released in honor of the Chinese New Year last year (not sure why these were sold in Vietnam instead of China). They released two burgers: the Spicy Kimchi Double Pork, which tops two pork patties with American cheese and kimchi, and the Spicy Szechuan Double Beef, two beef patties topped with American cheese, onions, tomatoes, and a spicy Szechuan-inspired sauce. 

Pancakes and sausage are a breakfast staple, but combining them into one oblong nugget meant to be dunked in syrup? Well, it does hit all the major food groups: salt, sugar, meat, and grease. 

One of the most legendary (and grossest) fast-food experiments in history, this baby sandwiched cheese and bacon in between two patties of fried chicken. How this actually made it to market is anyone's guess, but we're assuming KFC's R&D headquarters is located inside a frat house. 

This offering, which was released in 2012, filled a bun with a burger patty, bacon, lettuce, slices of Japanese pumpkin (also known as kabocha squash), and a nut sauce made with peanuts, almonds, cashews, hazelnuts, and sesame seeds. We can't even imagine what this one must have tasted like. 

A seasonal item with a cult following since its release in 1993, the Gracoro Burger is a real oddball. Instead of a burger patty, there's a patty of macaroni, shrimp, and white sauce, with a breadcrumb crust. It's topped with cheese, lettuce, and a mysterious brown sauce.
