Yeah, everybody has done the mayonaisse, mustard, ketchup deal but what alternative burger toppings or sauces are you down with?
I've become a big fan of a regular Hamburger (no melted cheese). Now, top that bad boy with some wing hot sauce and blue cheese dreesing. I also add lettuce, onion and sometimes tomato.
As far as regular cheeseburgers, add some Texas Pete.
Wendy's? Get a packet or two of their Chili sauce. Add a few drops to each bite to give the burger a little more zip.
