I don’t think I need to say much to convince you to make this roast flank steak roll with porcini and herbed butter and that it is the most delicious meat dish in the entire universe! This has been in my recipe queque for a long time and the majority of the reason is because I have felt pretty intimidated by having to butterfly the meat. I was mainly afraid of not cutting it to the same thickness and also afraid of cutting a hole in it. There were a few holes but nothing that kept the stuffing from falling out nor altering the flavor. The rest was super easy, just a bit time consuming…but it was all worth it in the end as I took each and every bite. The butter really puts a nice finish to this meat dish..so much so I could eat the butter alone. Hahahah!
