Wow! The caramelized onions and mushrooms were AMAZING! I added a little red wine to the sauce as well. We ate it over grilled steaks instead of as a sandwich, but I can see myself using this recipe for a lot of different things! Thanks!

I used sandwich rolls toasted with some garlic butter. We used our skillet to saute up the steaks and mushroom. Excellent sandwich....thanks for sharing!

Yummy sandwich! I used some leftover steak and a sandwich roll because I didn't have any rye. This was simple to put together and tasted great. Thanks Pneuma. Made for I Recommend Tag.
