Seems like the old standby combo of patty with lettuce and tomato just won't cut it anymore for the hamburger peddlers at the fast-food chains.
We've now got the pastrami burger and the Philly Cheesesteak burger (Carl's Jr.), the up-and-coming Angus Burger (McDonald's and Burger King), the Sirloin Burger (Jack in the Box), and of course the tried-and-true iterations of bacon/guacamole,jalapeno, and cheese burgers that most fast-food places offer in one version or another.
Of course, we can't leave out simply going to extremes, as in adding more meat patties (Burger King Stackers or the In-N-Out double-double).
So what's next?
How about a Hamburger with Chicken Breast?
How about a Spam Burger -- a nice thick hamburger patty topped off with a slice of Spam?
Maybe a hamburger garnished with chopped liver? Or is that too exotic for the masses?
Burger with salami? Or pepperoni? Or maybe sliced up hotdogs a la a Chicago dog?
