I use some cheap italian salad dressing, pour most of the oil off of it and marinade the steaks in that for about 30 minutes.
I've got a cast iron skillet on the grill that I through some sliced onions and mushrooms in...those are marinaded in a olive oil/balsamic vinegar type deal...then after they are nicely browned, scoop it on your steaks.
