Very good, and very easy! I cut this down to make just one steak. For the filling, I used 1 T butter, 1 sliced clove of garlic, 1 cremini mushroom, a bit of dehydrated chanterelle and porcini, and about 1/2 teaspoon of fresh parsley. I chose a fat sirloin for the steak. This was excellent. I had no problems with the filling staying in the steak, and I really enjoyed the flavors of mushrooms in every bite. Thanks for posting a great steak recipe!
Followed this recipe as listed except for using regular mushrooms instead of wild ones. This turned out perfectly, thanks for sharing your lovely recipe :)
Wow! These were great! Loved the mushroom and garlic flavor with the sirloin steaks! This biggest problem I had was with the mushrooms escaping on the grill! I made plenty of rescues. I used baby portabella rather than the mixed wild as that was what I had on hand. Made for Spring 2009 Photo tag.
