Grilled Steak with Garlic Butter Mushrooms

"This Grilled Steak with Garlic Butter Mushrooms is a recipe that the whole family loved. We were looking for something to make for dinner the other night and then I remembered that we had a couple of NY strip loin steak in the freezer. OK, that was a start, but I wanted to do a little more. I started thinking what goes great with a grilled steak? When I think about those old fashioned steak houses I always picture their steaks with a dollop of garlic butter on top. Although there had to be more; mushrooms, yes sautéed mushrooms, which was what it needed."
