Hamburger Toppings Final Question [POLL]

So far, Q106.5 listeners have Lettuce followed by Tomatoes, pickles then onions as the vegetables.  And prefer Ketchup as the condiment.  The Grub Hub Survey has Pickles ahead.  And Mayo as the #1 condiment for hamburger.

Let's turn that hamburger into a cheeseburger.  What's your choice of cheese?

Don't want to influence you, but Grub Hub picked American as the favorite.
