10. The Supreme Nacho Burger
Slater's 50/50, San Diego
Approximate Calorie Count: 1852
It starts with a beef patty flavored with taco spices, gets laid on a bed of shredded cheddar atop a flour tortilla before being loaded up with tomato, onion, salsa, black beans, guacamole, a pile of bacon, and house-made seasoned tortilla chips. That's all wrapped up, washed in egg, deep-fried (!), and hit with nacho cheese, sour cream, and pickled jalapeños. It's delicious, beautiful, and it will kill you.
