Of course this is really "Marlboro Man's favorite sandwich" from The Pioneer Woman. But I just felt too silly to call it that.
It really is a
butter-laden monstrosity wonderful sandwich that the whole family enjoyed. I love the "au jus" that goes along with it...sorta like a kicked up french dip.
Here's PW's recipe. I'll admit that I didn't use quite as much butter as she did, I just toasted the buns instead of grilling them, and I added a little red wine to the final product and simmered it just a bit.
