What is Your Favorite Hamburger Topping? [Poll]

Today, May 28th is "Hamburger Day", a way of celebrating one of America's favorite foods.  You don't have to tell me twice to go out and eat a delicious, juicy hamburger!  I'm a big fan of loading it up with toppings: lettuce, tomato, onion, pickles and my favorite condiment --a homemade aioli made with mayo and sweet garlic chili sauce to give it a kick.  My mouth is watering just thinking about it!
