I use all different kinds of seasoning depending on what I'm in the mood for, but some onion salt and fresh ground pepper is almost always part of it, mixed with something wet (bbq sauce, A1, What'sthishere Sauce). Nothing "mixed" with the meat either...just brushed on before grilling.

Key note: when forming the patties, I always make them sort of concave, the outer ring bulging. THat way as the meat cooks any swelling in the center is bringing it to the thickness of the outer ring.

Medium Rare to Medium...mmmmm
