re: how do you season your burgers?

IMHO, its better to keep it to salt and pepper, because a burger is one of the few items its perfectly acceptable to put ANYTHING on.

There is no reason to do anything special to a good burger when your accepted toppings can be anything from garlic puree to pineapple to every kind of cheese to every kind of sauce to every homemade or store bought condiment or salad item you can think of.
