My absolutely favorite sandwich in the whole world is a hamburger.  Especially with cheese.
I am right there with you.  I love hambergers.  I can eat them all year around
How do you like yours?  Fried in a pan, or flame grilled?
I always prefer flame grilled.  Something about the flame just adds an extra little something
I usually like to load up on toppings, but if it's good enough you won't need much in the way of ketchup or onions.  Sometimes even cheese won't be necessary.
